AD8361
Overview
The AD8361 is a mean-responding power detector intended for use in high-frequency receiver and transmitter signal chains up to 2.5GHz. It provides a linear-responding DC output voltage proportional to the RMS value of the input waveform, making it suitable for complex modulation schemes like CDMA and W-CDMA. The device operates from a single supply between 2.7V and 5.5V while drawing only 1.1mA of current.
Why Choose This Part
The device offers a true-RMS response for signals with high crest factors and maintains high accuracy of +/-0.25dB. It features excellent temperature stability and a rapid power-down mode that reduces current consumption to 1uA, making it ideal for battery-operated portable RF devices.

Key Specifications
Getting Started
When designing with the AD8361, ensure proper input matching and AC coupling to the RF input pin for optimal sensitivity. The AD8361-EVALZ evaluation board is available for rapid prototyping of the MSOP package version and includes SMA connectors for easy integration with standard RF test equipment.
