AD8362-EVAL Datasheet PDF - ADI

●GENERAL DESCRIPTION

●The AD8362 is a true rms-responding power detector that has a 60 dB measurement range. It is intended for use in a variety of high frequency communication systems and in instrumentation requiring an accurate response to signal power. It is easy to use, requiring only a single supply of 5 V and a few capacitors. It can operate from arbitrarily low frequencies to over 2.7 GHz and can accept inputs that have rms values from 1 mV to at least 1 V rms, with peak crest factors of up to 6, exceeding the requirements for accurate measurement of CDMA signals.

●FEATURES
