GENERAL DESCRIPTION

The ADL5502 is a mean-responding (true rms) power detector in combination with an envelope detector to accurately determine the crest factor of a modulated signal. It can be used in high frequency receiver and transmitter signal chains from 450 MHz to 6 GHz with envelope bandwidths over 10 MHz. Requiring only a single supply between 2.5 V and 3.3 V, the detector draws less than 3 mA. The input is internally ac-coupled and has a nominal input impedance of 500 Ω.
