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 $\mu$mSiGe 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 ($\approx$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.
