Abstract
Advancements in SiGe device development enable the realization of 76.5 GHz FMCW automotive long range radar systems using relatively low-cost silicon technology. This paper presents fully integrated receiver (RX) and transmitter (TX) circuits for wide temperature range operations. The TX chips consists of a VCO with two stage power amplifier, frequency divider chain, power detector circuit and operational amplifier to on-chip compensate the temperature drift of the center frequency. The RX chips is based on a 38.25 GHz doubler, a 76.5 GHz LNA, a passive balun, a fully balanced mixer and IF buffer. Also the integration and combination with planar patched antennas on a demonstrator board was discussed.
