A 200 GHz InP HBT Direct-Conversion LO-Phase-Shifted Transmitter/Receiver with 15 dBm Output Power

Fully-integrated 200 GHz direct-conversion transmitter and receiver ICs in InP-HBT process are presented. The transmitter exhibits > 20 dB conversion gain for 190–217 GHz, with 16.5 dBm / 15.3 dBm saturated output power at 195 GHz / 200 GHz, consuming 1,250 mW. The receiver has >15dB conversion gain over 190–213 GHz, 825 mW dissipation, and 7.7-9.3 dB noise figure over 200–212 GHz. An LO phase shifter enables sets of these ICs to form phased-array transceivers.
