2.7GHz AD8302 RF Amplitude and Phase Detector Logarithmic Detector Module

Device introduction 1 The relative amplitude and phase detector of radio frequency signal using AD8302 chip is a fully integrated RFIC used to measure the amplitude and phase between two independent input signals The operating frequency of this device can be from low frequency to 2 7GHz Can be used for gain detection standing wave ratio measurement 2 AD8302 built in two precision matched broadband logarithmic amplifiers a broadband linear multiplier phase detector 1 8V precision reference voltage source and analog output proportional operation circuit The input signal range is 60dBm to 0dBm reference impedance 5092 and the corresponding dynamic range is 60dB The AD8302 output provides accurate amplitude in the range of 30dB with a slope of 30mV phase value ranging from 0 to 180° and a slope of 10mV degrees 3 AD8302 is a monolithic integrated circuit used for RFIF amplitude and phase measurement It is mainly composed of two precision matched broadband logarithmic detectors a phase detector an output amplifier group a bias unit and an output reference voltage buffer The composition can simultaneously measure the amplitude ratio and phase difference between two input signals in the frequency range from low frequency to 2 7GHz which can be applied to the measurement of the linear ratio of RFIF power amplifiers the precise control of RF power the measurement of standing wave ratio and the measurement of remote systems Monitoring and diagnosis etc 4
