MAX2202EWTT10中文资料美信数据手册PDF规格书

General 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.
