“…Then, by choosing a field effect transistor (FET) as the only nonlinear device, a transceiver circuit was designed and demonstrated simultaneously as an amplifier and a resistive mixer at around 10 GHz [10]. Using it as the prototype, a balanced FMCW transceiver is presented with improved AM noise performance [11]. Again, in [3], the measured IF noise power is largely suppressed from the balanced transceiver module compared to the unbalanced one.…”

A 110-170 GHz transceiver is designed and fabricated in a 130 nm SiGe BiCMOS technology. The transceiver operates as an amplifier for transmitting and simultaneously as a fundamental mixer for receiving. In a measured frequency range of 120-160 GHz, a typical output power of 0 dBm is obtained with an input power of +3 dBm. As a fundamental mixer, a conversion gain of-9 dB is obtained at 130 GHz LO, and a noise figure of 19 dB is achieved. The transceiver is successfully demonstrated as a FMCW radar front-end for distance measurement. With a chirp rate of 1.6×10 12 Hz/s and a bandwidth of 14.4 GHz, a range resolution of 2.8 cm is demonstrated, and transmission test is shown on different objects.
