The receiver consists of a 245 GHz on-chip folded dipole antenna, a CB（common base） LNA, a 2 nd transconductance SHM（subharmonic mixer）, and a 120 GHz push-push VCO with 1/64 divider. The receiver is fabricated in f;/f;= 300/500 GHz SiGe:C BiCMOS technology. The receiver dissipates a low power of 288 mW.Integrated with the on-chip antenna, the receiver is measured on-chip with a conversion gain of 15 dB, a bandwidth of 15 GHz, and the chip will be utilized in PCB board design for gas spectroscopy sensor application.展开更多
