Maxim Integrated Products’ MAX2204 is a linear power detector designed to compensate for temperature and process shifts, reducing output variation to ±0.5 dB at full power (5 dBm) and to ±1.5 dB at low power (-16 dBm). This enables fewer end-of-line calibration tests during handset manufacturing. The device is suited for HSDPA/HSUPA, WCDMA, and cdma2000 handsets

The IC uses a silicon bipolar technology and operates from 450 MHz to 2.5 GHz. It also supports both resistive-tapping and directional-coupler architectures. The use of an external termination at the input of the device allows a single MAX2204 to be connected to multiple directional couplers.

Housed in a 2 mm x 2.2 mm 5-pin SC70 package, the MAX2204 is priced at $0.39 for 10,000 pieces. An evaluation kit is also available.
