Abstract

This article presents a four-element phased-array transceiver (TRX) front-end for millimeter-wave (mm-Wave) 5G new radio (NR). The effects of amplitude-to-phase (AM–PM) and amplitude-to-amplitude (AM–AM) distortions on error vec- tor magnitude (EVM) are detailed. A three-stage highly linear wideband class-AB power ampliﬁer (PA) is described, miti- gating AM–PM and AM–AM distortions without degrading other performances. A matching network embedded transmit- ting/receiving (T/R) switch is proposed
