Integrated Power Detection Architecture for mmWave 5G Transmitter

Abstract

This article presents the architecture of an output power control subsystem integrated into the transmission chain of a 5G mmWave communication station. The subsystem incorporates a power amplifier, antenna system, directional coupler, and RMS power detector to enable real-time monitoring and voltage signal translation. The directional coupler design effectively samples the mmWave signal, while the power detector facilitates accurate average power estimation. Our simulation results validate the system’s potential for enhancing power management and communication performance.
