16 Glossary Actuator An actuator is the electromechanical mechanism that transfers the RF contacts from one position to another upon DC command. Arc Suppression Diode A diode is connected in parallel with the coil. This diode limits the reverse EMF spike generated when the coil deenergizes to 0.7 volts. The diode cathode is connected to the positive side of the coil and the anode is connected to the negative side. Attenuator Switch This is a two-port device with two states, low-loss and precision high-loss state. The low-loss state has insertion loss typically less than.5 db. The high-loss state is a precision level of attenuation, such as 10, 20, 30 db, etc. These switches provide a means to increase the dynamic range of a system. Date Code All switches are marked with either a unique serial number or a date code. Date codes are in accordance with MIL- STD-1285 Paragraph and consists of four digits. The first two digits define the year and the last two digits define the week of the year (YYWW). Thus, 0532 identifies switches that passed through final inspection during the 32nd week of Failsafe A failsafe switch reverts to the default or failsafe position when the actuating voltage is removed. This is realized by a return spring within the drive mechanism. This type of switch requires the continuous application of operating voltage to select and hold any position. (Multi-position switches are normally open with no voltage applied). A latching switch remains in the selected position whether or not voltage is maintained. This can be accomplished with either a magnetic or mechanical latching mechanism. Indicator Indicators tell the system which position the switch is in. Other names for indicators are telemetry contacts or tellback circuit. Indicators are usually a set of internally mounted DC contacts linked to the actuator. They can be wired to digital input lines, status lights, or interlocks. Unless otherwise specified, the maximum indicator contact rating is 30 Vdc, 50 ma, and 1.5 Watts into a resistive load. Internal Termination Unselected ports are connected internally to a matched load. The load is a 50-Ohm resistive device. The max RF power rating is 2 watts CW. Without the internal termination option, the unselected ports are open circuits. Isolation Isolation is the measure of the power level at the output connector of an unconnected RF channel as referenced to the power at the input connector. It is specified in db below the input power level. Multi-Throw Switch A multi-throw switch is a switch with one input and three or more output ports. Standard Teledyne Relays switches (CCR-38, CCR-58, CCS-18, CCT-38, and CCT-58) provide up to 6 outputs from a single input. Multi-Throw Switch DUAL PULSE SWITCHING COMMAND CHARACTERISTICS: 1.

I 2 CURRENT PULSE (SEE NOTE 6) SWITCHING TIME (MONITOR RF CONTACT): T4 AND T5 = 20 msec MAX Self-Cutoff The self-cutoff option disables the actuator current in a latching switch. Either a series contact (linked to the actuator) or an IC driver circuit provides the current cutoff. This option results in minimum power consumption by the RF switch. Cutthroat is another name used in the industry for this option. Pulse latching is a term sometimes used to describe a switch without this feature. SPDT Switch A single-pole double-throw switch has one input and two output ports. Switching Time Switching time is the total interval beginning with the arrival of the leading edge of the command pulse at the switch DC input and ending with the completion of the switch transfer, including contact bounce. It consists of three parts: (1) inductive delay in the coil, (2) transfer time of the physical movement of the contacts, and (3) the bounce time of the RF contacts. Transfer Switch A four-port switch consisting of two independent pairs of RF paths. These pairs are actuated simultaneously. This actuation is similar to that of a doublepole double-throw switch. See application notes for typical usage. Page 14 Specifications are subject to change without notice 2005 TELEDYNE RELAYS

17 Glossary TTL Switch Driver Option As a special option, switch drivers can be provided for both failsafe and latching switches, which are compatible with industry-standard low-power Schottky TTL circuits. T-Option This option is for TTL Driver. There is one control input for each position. See the logic table below. TD-Option This option includes a decoder. The 3-bit parallel command is decoded to internally select the appropriate position. See the logic table below. The TD-Option increases the Vsw supply current demand by 50mA max at 28 Vdc and +20 C. Failsafe uses 1 circuit. uses 2 circuits (Vsw & C are common to both circuits).

18 Applications Performance Parameters vs Frequency Generally speaking, the RF performance of coaxial switches is frequency dependent. With increasing frequency, VSWR and insertion loss increase while isolation decreases. All data sheets specify these three parameters as worst case at the highest operating frequency. If the switch is to be used over a limited frequency band, better performance can be achieved. Actuator Current vs Temperature The resistance of the actuator coil varies as a function of temperature. There is an inverse relationship between the operating temperature of the switch and the actuator drive current. For switches operating at 28 VDC, the approximate actuator drive current at temperature, T, can be calculated using the equation: Where: I T I T = I A [ (T-20)] = Actuator current at temperature, T I A = Room temperature actuator current see catalog specification page T = Temperature of interest in C Series Application of Multi-Throw Switches This example shows a single-pole 9-throw unit made up of four 3-throw switches. The number of throws possible using this technique is essentially unlimited and is equal to the total number of throws available in the output stage. If a twostage unit were set up using six position switches, the resultant would be a total of 36 outputs or a SP36T switch bank. See Fig. 2. In SP3T Figure 1 Transfer Switch The transfer switch is essentially a modified double-pole-double-throw (DPDT) device. However, a true DPDT switch is a six port device that contains two totally independent transmission paths. In a transfer switch two transmission paths are provided but they are not totally independent as illustrated in Fig Out Circuit Insertion A complete microwave circuit or circuit element can be inserted into a transmission line by using a transfer switch as shown in Fig. 4. In Figure 4 1 Circuit 2 4 In the event that the 1-3 shorting of the microwave circuit is undesirable, this leg can be left out. 3 Out Magnetic Sensitivity An electro-mechanical switch can be sensitive to ferrous materials and external magnetic fields. Neighboring ferrous materials should be permitted no closer than 0.5 inches and adjacent external magnetic fields should be limited to a flux density of less than 5 Gauss. 1 2 Figure 2 DPDT Transfer 3 4 Pos. 1 connection Pos. 2 connection Examples of applications of the transfer switch are as follows: Two Transmitters to Either of Two Antennas Two microwave transmitters can be connected to either of two alternate antennas as shown in Fig. 3.
