Abstract:

A 35-GHz transmitter (TX) and receiver (RX) front end in CMOS technology for Ka-band frequency-modulated continuous wave (FMCW) phased-array radar transceivers are presented in this article. While typical FMCW phased-array radar transceivers use RF-path phase-shifting scheme for both TX and RX front ends, the Ka-band TX and RX front ends presented in this article are designed for TX-analog and RX-digital beamforming phased-array radar system. The link budget for the Ka-band phased-array radar transceiver is investigated. In order to improve the TX output power level, a power amplifier (PA) with a four-way power splitter/combiner is introduced. The detailed analyses and design considerations of the PA are investigated. The proposed TX and RX front ends are implemented and fabricated in a 1P9M 65-nm CMOS technology. The measured TX output power is 19 dBm. To the best of authors' knowledge, it is the highest output power FMCW module at the Ka-band using CMOS technology reported so far. The RX achieves a conversion gain of 29.6 dB. The TX occupies 1.42 mm(2) and consumes 588 mW. The RX occupies 0.59 mm(2) and consumes 72 mW.
