245-GHz subharmonic receiver in SiGe Mao, Yanfei Schmalz, Klaus Borngräber, Johannes Scheytt, Christoph A subharmonic receiver for sensing applications in the 245 GHz ISM band has been proposed. The receiver consists of a single-ended common base LNA, a 60 GHz push-push VCO with 1/32 divider, a transconductance 4th subharmonic mixer and IF amplifier. The receiver is fabricated in fT/fmax=300/500 GHz SiGe: C BiCMOS technology. Its measured single-ended gain is 21 dB at 243 GHz with tuning range of 12 GHz, and the single- side band noise figure is 32 dB. The input 1-dB compression point is at -37 dBm. The receiver dissipates a power of 358 mW.
