• A fully integrated, miniaturized, low-power frequency-modulated continuous wave (FMCW) multifunction chip realized by typical 1P6M 0.18 mum deep n-well CMOS technology is presented for the first time. The multifunction chip consists of VCO, buffer amplifier, 3-dB power divider, isolators, driving amplifiers, mixer, low-noise amplifier, attenuator, etc., necessary for carrying out the X-band RF signal processing of the FMCW signals interfaced to dual antenna arrays. The chip real estate measures 2.4 mm by 1.3 mm. The entire FMCW chip design is based on the synthetic complementary-conducting-strips (CCS) quasi-TEM transmission line. The transmitter output is 3.5 dBm for frequencies between 9.5-11.0 GHz and maximum tuning bandwidth is nearly 150 MHz. The receiver channel has conversion gain of 6 dB. The calculated range is in good agreement with the measurement data
