A Wideband Four-Channel SiGe D-Band Transceiver MMIC for TDM MIMO FMCW Radar

This paper presents a wideband D-Band transceiver MMIC in Infineon's 0.13 μmSiGe BiCMOS technology BIIHFC. The MMIC has four channels and is designed for an FMCW MIMO radar application with Time Division Multiplexing. Each channel can either be operated as a transmitter or a receiver. Measurements show a maximum transmitted power of 4. 6dBm and a harmonic rejection of 32.5 dBc at the center frequency (133GHz). The corresponding 3-dB bandwidth covers a range of 42.5 GHz from 111.5 GHz to 154 GHz. If a channel is operated as a receiver, a maximum voltage gain of 26. 5dB, an input referred 1-dB compression point above -13.5dBm, and a 3-dB bandwidth of 42 GHz (114 GHz -156 GHz) are exhibited.
