Abstract

This brief presents a 26.5–29.5 GHz dual-polarized 8-element Doherty phased-array transceiver front-end (TRX FE) for 5G applications. A 7-bit all-pass network (APN) phase shifter with <0.63°> $6.15\times 4.06~\text {mm}^{2}$ and consumes 350/74 mW in TX/RX mode, respectively, offering a power-efficient and high-resolution phase-shifting solution for large-scale phased-array systems on bulk CMOS platforms.
