AD8361ARM Datasheet Summary
General Description
The AD8361ARM is a high-frequency, true power detector intended for use in receiver and transmitter signal chains up to 2.5 GHz. It offers a calibrated RMS response with outstanding temperature stability and a broad dynamic range. The AD8361ARM is especially valuable for measuring high crest-factor signals, such as those encountered in CDMA and W-CDMA systems. It operates from a single supply voltage ranging from 2.7 V to 5.5 V and boasts low power consumption and fast power-down capability.

Features
