A Highly Integrated 60-GHz 6-Channel Transceiver Chip in 0.35 µm SiGe Technology for Smart Sensing and Short-Range Communications

This work presents a highly integrated 57-64 GHz 4-channel receiver (Rx) 2-channel transmitter (Tx) chip targeting short range sensing and large bandwidth communications. The chip features a wide tuning range integrated VCO with a measured phase noise lower than 80 dBc/Hz at 100 kHz offset. Each of the differential Tx channels shows a measured output power of 2-5dBm over the complete frequency range. In addition one Tx channel features a modulator that can be digitally programmed to operate in either radar or communication mode. Each of the receiver channels has a measured conversion gain (CG) of 19 dB, a single-sideband noise figure (NFssb) of less than 10 dB and an input referred 1-dB compression point (P-1dB) of less than 10 dBm. With all channels turned on the chip consumes a current of 300mA from a 3.3V supply.
