Overview
The AD8361ARMZ is a mean-responding power detector produced by Analog Devices Inc., designed for true power measurement of simple and complex waveforms in high-frequency receiver and transmitter signal chains. It operates up to 2.5 GHz and is particularly useful for measuring high crest-factor signals such as CDMA and W-CDMA. The device is easy to apply, requiring a single supply voltage between 2.7 V and 5.5 V, along with a power supply decoupling capacitor and an input coupling capacitor in most applications.
