RMS Power Detector

MAX02

General Description

Features

♦ -29dBm to 0dBm Power-Detection Range

♦ 33mV/dB (typ) Log Detector

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

♦ 0.1dB (typ) RMS Accuracy from WCDMA

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 out-

put voltage.

Modulation Change

♦

0.ꢀdB Detection ꢁrror Due to ꢂemperature

♦ +2.5V to +ꢀ.2V Single-Supply Operation

♦ Space-Saving 6-Bump WLP Package

The device operates from a 2.5V to 4.2V supply and is

specified over the -40°C to +85°C extended tempera-

ture range. The device is available in a 6-bump WLP

package.
