Overview
The AD8361ARTZ-RL7, produced by Analog Devices Inc., is a mean-responding power detector designed for accurate RF power detection in high-frequency receiver and transmitter signal chains up to 2.5 GHz. This device is particularly useful for measuring true power of simple and complex waveforms, including those with high crest factors such as CDMA and W-CDMA signals. It operates with a single supply voltage between 2.7 V and 5.5 V and requires minimal external components, making it easy to integrate into various RF systems.
