- W2186371192 abstract "Single-chip 60GHztransmitter (TX)andreceiver (RX)MMICshavebeendesigned andcharacterized ina0.15,um, '120 GHz fT/>200GHzfMAxGaAsmHEMT MMIC process. Thispaperdescribes thesecond generation ofsingle-chip TX and RX MMICs developed inourgroup.Comparedtoourfirst designs ina commercial pHEMT technology, theMMICs presented inthispapershowthesamehighlevel ofintegration butoccupysmaller chipareaandhavehigher gainandoutput poweratonlyhalfoftheDC powerconsumption. Thesystem operates withanLO signal intherange7- 8GHz.ThisLO signal ismultiplied inanintegrated multiply-by-eight (X8)LO chain, resulting inanIFcenter frequency of2.5GHz. Thesingle chipTX MMIC consists ofa balanced resistive mixerwithanintegrated ultra wideband IFbalun, athree-stage amplifier andtheX8LO chain. TheX8isamultifunction design byitself consisting ofa quadrupler, a feedbackamplifier, a doubler, anda buffer amplifier. TheTX chipdelivers 4.1± 1.5dBm overanRF frequency rangeof56.5to64.5GHz.The peakoutput poweris5.6dBm measured at60GHz andthe overall TXchip consumes 420mW ofDC power. Thesingle chipRX MMIC contains athree-stage lownoise amplifier, an imagereject mixerwithan integrated ultra wideband IFhybrid andthesameX8asusedintheTX chip. The RX chiphasmorethan10.7dBgainbetween 54.5and64.5GHz andmorethan13dBofimagerejection ratio between 57.5and 67.5GHzwithapeakimagerejection ratio of22.5dBat64GHz. Theinput referred third orderintercept point, IIP3ismeasured to-10dBmat60GHzandtheoverall RX chip consumes 450mW ofDC power.
