Abstract

A 17 GHz RF receiver consisting of an LNA and doubly-balanced mixers coupled by a monolithic 3.7:1 step-down transformer realizes over 70 dB of image-rejection in a 100 GHz-f_T SiGe BiCMOS technology. Quadrature LO signals are generated with electronically tunable phase from a subharmonically injection-locked oscillator. The measured IIP3 is -5.1 dBm with 17.3 dB conversion gain and 6.5 dB NF (SSB, 50 Ω) at 17.2 GHz. The 1.9×1.0 mm² IC consumes 62.5 mW from a 2.2 V supply.
