A 37–43.5-GHz fully integrated 16-element phased-array transceiver with 64-QAM 7.2-Gb/s data rates supporting dual-polarized MIMO
Résumé
This paper presents a fully-integrated 16-element phased-array transceiver (TRX) supporting dual-polarized multi-input multi-output (DP-MIMO). Transmitting/receiving (T/R) switches are embedded for time division duplexing (TDD) operation. High linearity bi-directional variable gain amplifiers (Bi-VGA) and passive phase shifters (PS) are designed for compact area and low power consumption, respectively. Fabricated in a 65-nm CMOS process, this TRX occupies an area of 25.76 mm 2 . With integrated frequency synthesizer, the TRX can work from 37 to 43.5 GHz, which can fully cover 5G NR FR2 n259 and n260 bands. In the receiver (RX) mode, a noise figure (NF) of 5.4-6.3 dB and a peak conversion gain (CG) of 27.3 dB are achieved. The transmitter (TX) mode achieves a peak CG of 48.7 dB, a 13.1-dBm OP1dB, and a 15.8-dBm Psat. By using 64-QAM modulation, measurement results show that the TRX achieves a data rate up to 7.2 Gb/s per independent data stream with 7.65 dBm output power per channel.
