摘要

A fifth-generation (5G) frequency range 2 (FR2) transmitter front end with a fully integrated power detector for enabling closed-loop power control is presented. The power detection path includes a miniature broad-side directional coupler, a sense pair, and a current-mode successive approximation analog-to-digital converter. The stacked power amplifier (PA) implemented in a 28-nm CMOS silicon on i...
