A transmitter IC for indoor presence and position detection based on radar is presented. The IC supports carrier frequencies between 45-67GHz, which includes the 60GHz ISM band. Wide RF bandwidth is achieved by applying low to moderate quality factor networks in the signal path. A bi-phase modulator multiplies the carrier with a pseudo-random data sequence of up to 4Gb/s for UWB signal generation. The 0.79mm2 IC produces >8dBm saturated output power and >25dB small-signal gain for frequencies from 35-67GHz. At 60GHz, the saturated (differential) output power is 10.7dBm. The IC dissipates 462mW from a 3.5V supply voltage and is implemented in a 0.13μm SiGe BiCMOS IC process.
