GENERAL DESCRIPTION

The AD8361 is a mean-respondingpower detectorfor use in highfrequencyreceiver and transmitter signal chains,upto 2.5 GHz.Itis veryeasy toapply.Itrequires a single supplyonly between 2.7 V and 5.5 V,a power supplydecouplingcapacitor, and an input couplingcapacitor in most applications. The output is a linear-responding dc voltage with a conversion gain of 7.5 V/V rms. An external filter capacitor can be added to increase the averaging time constant.

FEATURES

Calibrated rms response

Excellent temperature stability

Up to 30 dB input range at2.5 GHz

700 mVrms, 10dBm, re 50Ω maximum input

±0.25 dB linearresponse up to 2.5 GHz

Single-supply operation: 2.7 V to 5.5 V

Low power: 3.3 mW at 3 Vsupply

Rapid power-down to less than 1 µA

APPLICATIONS

Measurement of CDMA, W-CDMA, QAM, other complex

modulation waveforms

RF transmitter or receiver power measurement
