A 122-168GHz Radar/Communication Fusion-Mode Transceiver with 30GHz Chirp Bandwidth, 13dBm Psat, and 8.3dBm OP1dB in 28nm CMOS
A D-band radar/communication fusion-mode transceiver featuring dual-function multiplexers, a two-point modulation (TPM) FMCW digital PLL with a dual-core DCO, wideband I/Q LO generators, current choking high-gain mixers, and a power-combining PA with high output power is implemented in 28nm CMOS. In the radar mode, the RF front-end demonstrates 46GHz bandwidth, and the on-chip PLL/LO generated FMCW chirp achieves a wide bandwidth of 30GHz and a fast slope of 30GHz/50μs. In the communication mode, the transceiver including analog baseband realizes 20GHz BW and the IRR is better than 40dB. The measured TX saturated Pout is 13 dBm and output P1dB is 8.3 dBm. The measured PLL phase noise is -112dBc/Hz at 1MHz offset from the 11.69GHz carrier. The TX-to-RX over-the-air (OTA) modulation-demodulation measurement with QPSK and 16QAM signals shows the EVM of -20.7dB and -19.7dB, respectively.
