10 SmartStep Subsystems & Accessries Frequency Translatrs Bradband Frequency Cverage Aerflex / Weinschel has numerus Frequency Translatr designs that cver frequency ranges f IF frequencies thrugh X- Band frequencies. These custm designed subsystems prvide several parallel, extremely lw phase nise cnversin paths. Specifically designed lw phase nise amplifiers, SRD's and divider circuits result in a superir frequency translatin capability. Filters are designed t the custmers needs t reduce spurius and harmnic cntent t extremely lw levels. These subsystems use frequency multipliers and mixers t generate a set f phase cherent lw phase nise carriers. Thrugh the use f ultra lw phase nise scillatrs driving distributin amplifiers supply the signals that are multiplied by varius N values and cmbined with mixers t achieve the custmer required frequencies with excellent phase nise. A bank f filters blck the undesired mixer/multiplier prducts.

22 SmartStep Subsystems & Accessries Lw Intermdulatin Subsystems & Signal Cnditining Netwrks... Sme custm subsystem designs warrant the use f Lw Intermdulatin passive cmpnents such as prgrammable attenuatrs, terminatins, fixed attenuatrs, cuplers, cables, cnnectrs and switches. Aerflex / Weinschel is a leading manufacturer f the first three items. The fllwing paragraphs briefly describe the imprtance f lw intermdulatin and sme design features and cmparative test data fr the same. Prgrammable Attenuatrs Histrically the mst demanding specificatins fr prgrammable cmpnents and subsystems have been lw insertin lss and SWR, cmbined with a reasnable life expectancy f several millin switching cycles. This was usually adequate fr RF instruments like spectrum analyzers and signal generatrs, where the attenuatr bandwidth rather than the switching speed was f prime cncern. T achieve wide bandwidths, the prgrammable attenuatrs were mstly f electrmechanical design and the linearity f these passive cmpnents was nly taken fr granted. Intermdulatin distrtin discussins and prblems were usually limited t cmpnents such as amplifiers, mixers and filters. In recent years, hwever, wireless cmmunicatin systems emplying cmplex digital mdulatin schemes, increased channel capacity, high transmit pwer and extremely lw receiver sensitivity have put int questin the linearity f passive cmpnents. Even very lw level multi-tne intermdulatin prducts generated by attenuatrs can seriusly degrade the efficiency f a system/instrument if these prducts fall within the user passband. Fr tw clsely spaced tnes at frequencies f1 and f2, the third rder IM prducts at 2f1 - f2 and 2f2 - f1, are the mst harmful distrtin prducts. They are harmful because they are clse t f1 and f2 and virtually impssible t filter ut. In tday's base statins the multi-carrier pwer amplifier (MCPA) is replacing banks f single-channel amplifiers and their crrespnding pwer cmbining netwrk. MCPAs have the capability f carrying a number f mdulatin schemes simultaneusly and can als emply schemes such as dynamic channel allcatin (DCA) t use the allcated frequency spectrum mre efficiently. The in-band intermdulatin distrtin (IMD) perfrmance f these amplifiers is extremely critical and needs t be measured using lw distrtin prgrammable multi-tne generatrs with superir IMD perfrmance. Thrugh IM3 (dbm) IM3 Perfrmance f Electrmechanical & Slid State Prgrammable Attenuatrs Passive IM3 Measurement Weinschel Series 4206, 4216, 3200 & 150 Lw Carrier Frequency: MHz High Carrier Frequency: MHz IM3 Frequency: MHz PIN switched series FET switched series TO5 rela y switched series Edge-line reed switched 150 series Input Pwer, P in (dbm) each tne Electrmechanical prgrammable attenuatrs bviusly prvide a far superir IMD perfrmance than their crrespnding slid state cunterparts emplying semicnductr switching elements. Hwever, their slw switch speed, in the rder f milli-secnds, and shrt switch life in the rder f 5-10 millin cycles make them unattractive in sme applicatins like cell phne testing and ther ATE systems. Slid State prgrammable attenuatrs d vercme these tw prblems and are, therefre, included here fr IMD perfrmance cmparisn. The gal is t prvide sme gd basic IMD test data fr a variety f cmmercial prgrammable attenuatrs and permit the end user t select the mst apprpriate type fr his system applicatin. Fixed Attenuatrs & Terminatins These seemingly linear cmpnents generate lw levels f IMD which must be cnsidered, especially when incident pwer levels are high. Sme f Aerflex / Weinschel custm subsystem designs include lw IM versins f medium and high pwer fixed attenuatrs and terminatins. These cmpnents are supplied with specified 3rd rder thrugh and reflected intermdulatin levels (IM3) measured with a passive IM analyzer. Typically, the IM3 levels fr these cmpnents are -110 dbc. Standard Mdels with this LIM (lw IM) ptin are mdels 33, 24, 49, 53, 57, 58 and the crrespnding terminatins, ranging in incident pwer ratings f 25 t 500 Watts. Features f these cmpnents include specifically designed cnnectrs and carefully prcessed and trimmed thin film resistrs fr lw IM perfrmance. Cuplers, Cables, Switches, Cnnectrs, etc. Fr these ther passive cmpnents Aerflex / Weinschel wrks very clsely with ur suppliers, prviding them pertinent design input t achieve the lwest pssible IMD perfrmance n such prducts. 158 web: weinschel-sales@aerflex.cm Revisin Date: 3/4/09
