Dual-Channel Single Sideband Transmitter in 45 nm CMOS SOI for a 70 GHz OFDM Radar

The advances in digital modulations for radar, like OFDM, show promising results. These modulation concepts benefit from high integration of analog and digital CMOS technology, as they rely on digital signal generation and processing. In this paper, a two-channel OFDM single sideband transmitter in CMOS SOI technology is presented. The chip performance is evaluated and broadband sideband suppression of the OFDM symbols using digital predistortion is demonstrated.
