MAX2202

RMS Power Detector

New Miniature RMS Power Detector with Improved Dynamic Range and Accuracy


Please check latest availability status for a specific part variant.

Description

The MAX2202 RMS power detector is designed to operate from 800MHz to 2.0GHz. The device is ideal for wideband code-division multiple access (WCDMA), cdma2000®, and high-speed downlink/uplink packet access. The device accepts an RF signal at the input and outputs the same voltage regardless of the peak-average of the input signal. The output voltage and input power is linear in dB. The device has a -29dBm to 0dBm detection range, and every dB change in input power gives 33mV (typ) change in output voltage.

The device operates from a 2.5V to 4.2V supply and is specified over the -40°C to +85°C extended temperature range. The device is available in a 6-bump WLP package.
