... The device has a -24dBm to +3dBm detection range, and every dB change in input power gives 35mV (typ) change in out- put voltage. The MAX2203 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. ...

... Note 2: Refer to Application Note 1891: Wafer-Level Packaging (WLP) and Its Applications . Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability ...

... The MAX2203 RMS power detector is designed to operate from 800MHz to 2.0GHz. The device is ideal for 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 Table 1. Peak-to-Average Ratio (PAR*) of Test Signals ...

... DETECT ENABLE BIAS MAX2203 The MAX2203 is not particularly sensitive to the layout since it only needs 3dBm for maximum output voltage. However, there are two areas that need attention: the GND pins and the supply bypassing. Connect the GND pins to the PCB ground with a ground via as close as possible, and bypass V as close as possible to the part ...
