Abstract :
A subharmonic receiver for 245 GHz spectroscopy sensor applications have been proposed. The receiver consists of a CB (common base) LNA, 2nd transconductance SHM (subharmonic mixer) and a 120 GHz push-push VCO with 1/64 divider. The receiver is fabricated in fT/fmax=300/500 GHz SiGe: C BiCMOS technology. Its measured single-ended gain is 14.3 dB at 245 GHz with tuning range of 15 GHz, and the single-side band noise figure is 19 dB. The input 1-dB compression point is at -24 dBm. The receiver dissipates a power of 200 mW.
