AD8302 Gain, Loss, and Phase Detector Module

The AD8302 phase and loss detection module is used for detecting phase difference. The phase difference detector chip AD8302 is the core component of the module, responsible for converting phase difference into voltage.

This phase difference detection module works by converting the phase difference between input and output signals into a voltage level for measurement.

The minimum detectable phase difference for this gain detection module is 1 degree.
