An integrated 60 GHz receiver front-end in SiGe:C BiCMOS

This paper presents a fully differential 60 GHz receiver front-end in SiGe:C technology. It comprises a differential LNA and a Gilbert mixer. The measured down-conversion gain is 28 dB. In the 57-64 GHz band the in-band gain ripple is less than 1 dB, and the output 1-dB compression point is -1.6 dBm. Measured and simulated results agree well over the whole range. The LNA draws 30 mA from a 2.2 V supply and the mixer core consumes 6 mA from 3 V supply. The receiver front-end will be part of an integrated WLAN transceiver in the 60 GHz band.
