A G-Band ASK Transceiver for Short-Range Communications in 130 nm SiGe BiCMOS

This paper presents a highly efficient G-band ASK transceiver integrated in a 130 nm SiGe BiCMOS process. The transceiver is intended for high data rate short-range wireless and wireline communication tests using on-board antennas/couplers. The designed transmitter (Tx) is able to upconvert NRZ modulated baseband signals with data rates up to 50 Gbps at a 200-GHz carrier frequency delivering to the differential antenna a simulated output power of 7.8 dBm. Also, a self-mixer based non-coherent receiver (Rx) with a simulated conversion gain of around 12 dB successfully recaptures the received modulated data after a simple low-pass filtering. The system consumes 65.7 mW in quiescence resulting in a remarkable energy efficiency of 0.36 pJ/bit for the Tx and 0.95 pJ/bit for the Rx in a single-channel 50 Gbps communication scenario.
