1 Keyight Tecnologie Cutom Switch Matrice Technical Overview

2 Introduction Over a period of more than ten year, Keyight Technologie, Inc. ha developed a tandard deign and manufacturing proce for making high-performance cutom witch matrice. Keyight deign matrice that are optimized for your application and pecification. Thi product note decribe what a witch matrix doe, and explain the advantage of uing a witch matrix in an RF/microwave tet ytem. It alo help you determine the critical parameter and other deign requirement for a matrix that will meet the need of your application. Electrical and mechanical pecification that have ignificant impact on matrix performance are analyzed, and different microwave witching deign are decribed. For each deign, we cover characteritic that could make one deign more uitable than another for your application. Finally, pecial feature and function that add value and eae of ue to your witch matrix are dicued. The Function of the Switch Matrix Virtually all automatic microwave tet ytem ue a computer-controlled coaxial witch matrix to route ignal between tet intrument and the device under tet (DUT). The matrix allow multiple meaurement to be made automatically, with a minimum number of manual connection to the DUT. A matrix can alo provide ignal conditioning by incorporating amplifier, filter, attenuator, and frequency tranlating device uch a mixer and multiplier. Since all timulu and repone ignal mut pa through the witch matrix, the characteritic of the matrix ignal path directly affect the accuracy and integrity of all meaurement. It i impoible to deign a witch matrix that doe not degrade the original ignal. However, the matrix can be optimized to meet the key performance requirement of the application. Keyight ue high-performance coaxial witche in all of it witch matrice, unle otherwie pecified by the cutomer. Keyight witche meet high tandard of performance, with exceptional reliability (>5 million cycle), repeatability (le than 0.0 db), VSWR (typically.:), and iolation (typically >90 db). In thi product note, electrical pecification aume the ue of Keyight witche in the matrice. Appendix B include pecification for ome of the mot popular Keyight witche. For complete information, refer to the RF and Microwave Tet Acceorie Catalog, publication number E.

3 Electrical Specification The electrical parameter decribed below are key pecification that hould be conidered when ordering a cutom witch matrix. By providing thee pecification you will help Keyight deign engineer make the bet deign choice for your application. Critical pecification hould be highlighted to enure that our deign complie with them. We ue our experience and the latet technology to meet or exceed your requirement. If a parameter i not pecified, we optimize the deign for the bet overall performance. The more completely you define your requirement, the better we can optimize your matrix for not only performance, but for price and feature, a well. VSWR VSWR in a witch matrix i directly related to the VSWR of the coaxial witche ued in the matrix. The VSWR of the witche i determined by the mechanical dimenion and tolerance ued in their manufacture. Keyight witche are manufactured with a mechanical tolerance of ± inch. Keyight witch matrice are deigned to avoid the wort-cae VSWR of the witche by electing witche optimized for the pecific frequency range of your application. VSWR i alo minimized by chooing cable length to prevent reflection from adding at pecific frequencie, and by the ue of low-ripple power divider where appropriate. If VSWR i a critical factor in your application, we can further minimize it by uing iolator or attenuator at the input and output port and at critical point in the RF path. Inertion lo Low inertion lo i important becaue power i expenive, epecially at high frequencie. The importance of inertion lo in your application depend on the power requirement of your DUT, the input and output power requirement of the timulu and repone intrument in the ytem, and noie conideration. Inertion lo i related to the witche and other component ued in the matrix, the cable that route the ignal and other apect of the deign. To minimize inertion lo in a critical path, the cable length of the enitive path can be minimized by careful placement of component near to each other and to input/output connector; alo, by election of coupler, iolator, and other component for the band of interet (rather than for unpecified wideband operation). A pecification that i important in many application i inertion lo ripple. Thi i a mall up and down variation (typically pecified over a narrow band) in the inertion lo, caued by VSWR reflection from component uch a divider and coupler. Ripple can be minimized by uing iolator and/or pad in key path. Ripple value of 0. db over a 00 MHz bandwidth at 8 GHz are typical of Keyight matrice.

In the above high iolation deign, RF hielding compartment eparate RF path providing 5 db in ignal iolation.

4 Iolation A witch matrix with high iolation help aure meaurement integrity, epecially if high- and low-power ignal are routed through the matrix imultaneouly. Iolation i the amount by which an unwanted ignal i attenuated before it i detected at the port of interet. For example, a matrix may have to route a ignal to a pectrum analyzer for meaurement at 70 dbm and to imultaneouly route another ignal at +0 dbm. Switche with 90 db or more iolation keep the meaurement integrity of the low-power ignal in thi example. Our experience ha led to the election of the type and manufacturer of connector, adapter, and other component that yield the highet iolation. In addition, for increaed iolation, ignal path may be eparated by uing multiple witche and careful routing. If your application i highly enitive to ignal cro talk in pecific path, we may place iolation hield around the enitive path and ue pecial component that are contructed with low RF leakage. Reliability The reliability of a witch matrix depend on the life of each of it witche and on the total number of witche ued. Keyight witche are guaranteed to meet pecification over 5 million cycle (typically 0 million). The following i a comparion of replacement frequencie for Keyight witche and witche with a lower pecified lifetime in an example application. Switch reliability comparion Thi example i a high-volume component or module tet application in which witche experience 5,000 cloure per 8-hour day (0 cloure/min.). Uing Keyight witche: replacement frequency = 5 million / 5,000 =,000 day = ~.7 year Uing witche with a lifetime of million cycle: replacement frequency =,000,000 / 5,000 = 00 day = 6 month Note that many witch manufacturer do not pecify the number of cycle over which the witch i guaranteed to meet pecification, but the number of cycle to detruction. Keyight guarantee that it witche will meet all pecification for a minimum of 5 million cycle. Keyight 870A,B,C 50 termination 6 RF port 5 C Keyight 8706A,B,C 6 5 C Figure.

5 Repeatability Repeatability i a meaure of the change in inertion lo or phae for a witch matrix path from cycle to cycle over time. Repeatability enure accurate tet reult. S-parameter repeatability i critical becaue it cannot be calibrated out with tet oftware. Inertion lo repeatability of Keyight witche i better than 0.0 db, and inertion lo repeatability of mot witch path through Keyight witch matrice i typically about 0.06 db, due to random averaging of cacaded repeatability. Phae repeatability i typically 0. degree per witch at 0 GHz. Termination A 50-ohm load termination i critical in many application, ince each unued egment of coax tranmiion line if unterminated at one end may reonate at a frequency where it i one-half wavelength long and at all higherfrequency harmonic. Thee reonance can uck out ignal power at high Q at pecific frequencie. Thi can be quite important when deigning a matrix up to 6 GHz or higher, where witch iolation drop coniderably. Terminating unelected tranmiion line egment prevent thi problem. Signal leakage into unterminated witche reduce iolation performance a well. In ome Keyight witche, uch a the 876, 870, and 8706 multi port witche, all port are matched. That i, any unelected port i witched to an internal 50-ohm load. Termination i important if reflected power from a ignal ource on a matrix input line would damage or affect the operation of the ource. Alo, if the input i one of a pair of line from a power plitter, the other line inertion lo ripple would be increaed by reflection on the firt unterminated line (ee Figure 8). Thu, when witche are at output of the power divider, unued port of the witche hould be terminated. However, termination i uually not needed when witching between repone intrument, ince if an intrument i not elected to be read, it doe not matter if the ignal routed to the intrument i noiy. If high VSWR i acceptable on ome unelected path, we can offer a lower-cot matrix by chooing unterminated witche and more flexible deign. Frequency of operation Keyight deign RF and microwave witch matrice that operate from DC to 50 GHz. By uing pecial connector and witche, we can deign for higher frequencie. Baed on your pecified frequency range of operation, we chooe a deign that i optimized for your requirement. The higher the frequency, the more critical the routing and cabling of the ignal become to meaurement integrity. Specifying a low-frequency limit i a important a pecifying a high-frequency limit, becaue wideband component are expenive and can have more inertion lo. Therefore, we recommend that you pecify the narrowet band poible for your application.

Thi witch matrix ha incorporated an ALC directional detector, a 7 db gain amplifier, everal directional coupler, a programmable attenuator, fixed attenuator, power plitter, and mixer. 5

6 Power pecification One advantage of uing a witch matrix in your ATE ytem i that ignal conditioning can be incorporated within the matrix. Baed on your power requirement, we may ue attenuator and/or amplifier to provide the optimized power to your DUT. Power enor can alo be coupled to the critical path for very accurate power meaurement. Equal path/equal phae Some application require equal length on everal path through the matrix. Since each equal path preent the ame tet condition to the DUT, in many application you can tet or calibrate one path and apply the reult to all the other DUT connected to other equal path. By uing CAD and automatic bending equipment to manufacture emi-rigid cable, Keyight can provide equal path within 0.05 inch for many application. Some application require equal path for amplitude match and ome for phae match. To meet very tight phae-match pecification, we ometime ue phae adjuter. In many cae, however, uing Keyight emi-rigid cable deigned for your application and performing extra teting to aure equal pecification provide phae match without expenive phae adjuter. For example, without uing phae adjuter, we can guarantee ignal in different path at 8 GHz to be within 0 degree. Switching peed Keyight microwave coaxial witche are break-beforemake witche. Switch peed i between 5 and 0 milliecond. We can deign regiter-baed driver for fater witching peed. For application that require even higher witching peed, we build matrice uing fat, olid-tate PIN witche, with a witching peed in the nanoecond range. Signal conditioning and matrix characterization A mentioned above, one advantage of having a witch matrix in a ytem i that ignal conditioning can be obtained within the matrix. We ue amplifier and attenuator to atify power requirement. Filter and iolator can be ued for electing or deleting a ignal through a pecific path. We alo ue phae- and frequency-tranlating device uch a mixer, doubler, and divider to provide the right frequency for operating the DUT or for up/down converion. Detector and noie ource may alo be intalled. Thee device are permanently connected with emi-rigid coaxial cable; no external cabling i needed. The reult i a compact, convenient, one-box olution. Some application require frequent calibration of the ATE ytem and the witch matrix. If your application require thi, we incorporate calibration and characterization path, and intall power enor in thee critical path.

7 Switch Driver Your cutom witch matrix can be controlled remotely through GPIB, uing witch drive intrument or device. If your application require another mode of control, uch a RS-, RS-, regiter-baed, or even cutom remote control, we can provide a quote for you. If your witch matrix i controlled through GPIB, then the 870A witch driver, 7A attenuator/witch driver, 88A witch control unit, or 706A witch/attenuator driver for MMS module can be ued to control the witche. The Keyight 870A i a rack-mounted driver, deigned to be incorporated into the ytem II mainframe to provide a complete witch matrix olution. The 870A doe not include manual control capabilty. The Keyight 7A can control a many a 0 witche and provide both the olenoid DC driver power and GPIB for automated programmability. It alo ha manual control and LED indicator. The Keyight 88A provide GPIB control for up to 80 witche, but require an external power upply. The Keyight 706A i a /8 module witch/attenuator driver, deigned to be incorporated into a Keyight modular meaurement ytem (MMS) mainframe. It ha graphical/ manual control capability to provide a total, integrated ATE olution. The Keyight EA i a regiter-baed VI general purpoe witch driver that can control up to 6 witche or channel. Refer to Appendix C for more information on Keyight witch driver. The olenoid control line from each witch in the matrix are typically routed to back panel connector for convenient connection to a Keyight 7A, 88A, 706A, or 870A. Keyight can alo integrate driver circuitry within the witch matrix, with all the neceary power upplie. However, if you chooe tandalone witch driver, our deigner need to know which witch driver you will be uing, ince each driver ue a different control logic. Switch Matrix Deign When pecifying a witch matrix for your ytem, firt determine how many input and output the matrix need. Thi i called an nxm matrix, where n i the number of input and m i the number of output. The next tep i to determine if each input need to be connected to one output or to everal output and if different path are activated imultaneouly or in equence. Thi important information help our deign engineer chooe a combination of the following three baic witch matrix deign. Common highway Feature: Can connect any input to any output Advantage: Simplet deign High iolation Lowet cot Wide bandwidth Diadvantage: Can connect to only one output at a time Higher inertion lo with large configuration Example pecification at GHz matrix in Figure 6.

9 Application pecific matrice A mentioned above, the final deign i uually a combination of the three baic matrice and other applicationpecific deign element to atify your electrical requirement. However, in ome cae, the final deign i very application pecific and doe not reemble any of the baic matrice. Figure i an example of a matrix deigned for component teting. Expanding a witch matrix If your ATE ytem require proviion for future expanion, we ue a building block deign (Figure 9 and 0) that leave unued terminal for later expanion of the matrix. Compared to imilar deign without the proviion for expanion, thi deign ue approximately 0 to 5 percent more witche and cable. The reult i a more flexible deign, but the cot i uually 0 to 5 percent higher. Alo, performance cannot be a highly optimized. Mechanical Specification Switch matrix platform Keyight cutom witch matrice are available in three different platform:. Rack-and-Stack (Keyight ytem II): The Keyight 8760 erie matrice are rack-mount boxe with connector type and location deigned to your pecification. If your application impoe ize and/or weight contraint on the matrix, pleae pecify thee. The frequency of operation i DC to 50 GHz.. VI: The Keyight E690 erie are cutom witch matrice in the VI platform. The frequency of operation i DC to 6.5 GHz.. MMS: Keyight provide cutom witch matrice up to 50 GHz in the MMS platform. Thee are the Keyight 706 erie matrice. In addition to thee cutom olution, Keyight offer a family of tandard MMS witch matrix module. Thee are the 706A/C and 706A/C. For more information on thee matrice, refer to the MMS catalog, publication number Input Expanion input Input Expanion output Input Output Figure 9. x Non-blocking full acce building block matrix Figure 0. 8 x 8 Non-blocking full acce building block matrix 9

10 Connector When ordering a matrix, pecify the RF connector. In addition to frequency range, the expected number of connection and diconnection determine the bet connector. Connector aver are recomended, ince ytem repeatability depend on good connection and the cot of replacing original connector i high. For application to 8 GHz, requet SMA connector if there i to be little connector wear. A low-cot connector aver i available from Keyight (part number 50-6, SMA male-to-sma female adapter). For greater durability, order Type-N or APC-7 connector. For operation up to 6.5 GHz, there are three alternative:. APC-.5 female connector with replaceable inner and outer conductor;. APC-.5 male connector with female-to-female adapter; and. APC-.5 male connector with a preciion adapter. Above 6.5 GHz, APC-. connector are uually required. Keyight can alo build matrice with Blind Mate connector and any other type of connector you requet. Readback, front panel chematic, and LED Matrice can be deigned in two way: with or without a proviion called readback for determining the poition of each witch and attenuator. Readback can be obtained in three way:. Immediate poition verification of the lat witching command by a Keyight 870A or 706A driver. Thi ene mode only occur after witching (peed i about 50 m) and cannot be ued a an interrogator at time other than immediately after witching. Software command for witching with thi readback ytem are lightly more complicated than without readback.. The Keyight 88A with 7A digital I/O card intalled can provide poition verification at any time uing the read or view command. The 88A alo ha manual puh-button capability. When the number of witche i high, the 88A become a more expenive driver olution than the 870A. If your choice of witch matrix platform i VI, VI I/O card are alo available.. Routing internal witch indicator circuit to a rear panel connector provide TTL high and low tate to be read by an external device. Thi external device can be a Keyight 88A with I/O card or a cutomized olution. Readback may be combined with front panel LED, which indicate witch and attenuator poition, and thee can be combined with a ilk-creened front panel ignal flow chematic. Thi feature i an excellent oftware and hardware troublehooting tool, ince the operator can tell at a glance which path i activated. Although it i a ueful feature, a front panel chematic can be expenive. Alo, the LED require extra engineering and aembly time for the DC wiring and circuitry required to drive them. Manual witche Matrice can alo be controlled manually uing front and back panel manual witche. Thi feature i attractive for application in which the ATE ytem mut be troublehot in a remote area. If you have the manual control option, you don t need to be in the computer room to change a path, ince all path may be elected from the matrix front panel. Since additional mechanical and electrical deign time i needed, a well a about 0 percent more aembly time, thi feature add cot to your matrix. 0

11 Ordering Proce Keyight accept order for cutom witch matrice in two way: build-to-print and build-to-pec. Build-to-print mean you provide the RF deign and Keyight build the matrix. However, there i uually ome additional engineering required to create DC chematic, a mechanical layout, aembly and tet procedure, and the cable deign for the automatic bending proce. Alo, in ome cae, Keyight deigner may ugget ome modification to the original deign to reduce cot and/ or add capabilitie. In the cae of build-to-print, we need a detailed RF chematic of the matrix and the bill of material. We guarantee that we will build the unit exactly a deigned. The pecification are therefore governed by your deign. When you contact your Keyight ale repreentative about a build-to-print order, he/he will ak you for the diagram and bill of material. The repreentative will then work with Keyight deigner to provide you with a formal propoal. In thi propoal, we define the deliverable, price and delivery of the unit. Keyight requet that a copy of the propoal igned by you accompany the order to enure agreement on the deliverable. In the cae of build-to-pec, you provide the pecification and Keyight deign, aemble, and deliver a complete olution. The Keyight repreentative will provide you a witch matrix pecification form to fill out. (Appendix A contain the witch matrix pecification form.) The anwer to the quetion on thi form give the engineer all the information needed to deign the optimized witch matrix and provide you a quote for price and delivery. If you have a written pecification, pleae include a copy along with the Keyight pecification form. Keyight will then provide a propoal baed on thi information. The propoal will include a block diagram of the deign, the guaranteed pecification and, if applicable, exception to ome parameter. In many cae, there will be a direct interaction between you and Keyight deigner to make ure we are deigning exactly what you need. We may alo make uggetion for price reduction or deign improvement. A in the build-to-print cae, Keyight require a igned copy of the propoal with the order. Upon receiving the order, Keyight deign the matrix baed on the agreed pecification. When the deign phae i complete, you get one more opportunity to review the deign and give your final approval before the fabrication phae begin. Deliverable Your cutom witch matrix i delivered to you with a complete ervice manual. The manual include RF chematic; DC wiring diagram; a complete part lit; front, rear, and internal mechanical layout; and all the information you need to ervice the unit. Concluion Keyight will deign and manufacture a cutom witch matrix for your ATE ytem uing the detailed information you provide on the witch matrix pecification form. Our expert ale and engineering team work with you during the deign phae to enure that your matrix i optimized for your application, with the feature and function that you require.
