W-band monolithic single sideband transceiver for automotive radar applications

This paper reports the first W-band monolithic single sideband FMCW transceiver with direct digital synthesizer modulation. This heterodyne transceiver improves the system sensitivity over the previously reported homodyne approach. The complete transceiver has better than 12-dB suppression of the image sideband with a nominal LO drive of 9 dBm and is estimated to exhibit a 11-dB noise figure for IF as low as 1 MHz. This MMIC chip was fabricated using TRW production line process and is suitable for automotive radar applications.
