Overview
The ADL5502ACBZ-P7, produced by Analog Devices Inc., is a highly versatile and accurate crest factor detector designed for use in high-frequency signal chains. This component combines the functions of a true rms (root mean square) power detector and an envelope detector, making it ideal for measuring the crest factor of complex modulation waveforms. It operates within a broad frequency range of 450 MHz to 6 GHz and supports envelope bandwidths up to 10 MHz. The device is known for its low power consumption, single-supply operation, and high accuracy in determining the rms and peak-to-average values of signals.
