Overview
19-4982; Rev 0; 10/09 KIT ATION EVALU E L B A AVAIL RMS Power Detector General Description The MAX2203 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 MAX2203 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 -24dBm to +3dBm detection range, and every dB change in input power gives 35mV (typ) change in output voltage.
The MAX2203 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.
