A differential broadband receiver equalizer targeting coaxial cable channels and data rates up to 70 Gbps was designed and fabricated in a 0.13 mum SiGe BiCMOS technology with fT of 230 GHz and fMAX of 280 GHz. The measured S-parameter response exhibits a single-ended peak gain of 12.2 dB at 52 GHz. The small signal frequency response is continuously adjustable to provide up to 31 dB of peaking between...
This paper describes the first demonstration of Doppler detection and data transmission at 140 GHz and 4 Gb/s through the air using a single-chip silicon transceiver at 140 GHz. The transceiver, which consists of a 140-GHz push-push VCO with a static divide-by-64 chain, a 140-GHz amplitude modulator, a 140-GHz LO amplifier, a fundamental frequency mixer, a 140-GHz LNA, and a variable gain IF amplifier,...
