AD8361 Datasheet | Analog Devices

FEATURES Calibrated rms response Excellent temperature stability Up to 30 d B input range at 2.5 GHz 700 m V rms, 10 d Bm, re 50 Ω maximum input ±0.25 d B linear response up to 2.5 GHz Single-supply operation: 2.7 V to 5.5 V Low power: 3.3 m W at 3 V supply Rapid power-down to less than 1 µA APPLICATIONS Measurement of CDMA, W-CDMA, QAM, other plex modulation waveforms RF transmitter or receiver power measurement GENERAL DESCRIPTION The AD8361 is a mean-responding power detector for use in high frequency receiver and transmitter signal chains, up to 2.5 GHz. It is very easy to apply. It requires a single supply only between 2.7 V and 5.5 V, a power supply decoupling capacitor, and an input coupling capacitor 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.
