An Integrated Bidirectional Bridge With Dual RMS Detectors For RF Power/ Return-Loss Measurement

By Eamon Nash and Eberhard Brunner

Directional couplers are used in a wide variety of applications to sense RF power, and they may appear at multiple points in a signal chain. In this article, we will explore the ADL5920, a new device from Analog Devices that combines a broadband directional bridge-based coupler with two rms responding detectors in a 5 mm × 5 mm surface-mount package.
