21st May - Maxim Integrated Products introduces the MAX2204, a linear power detector for mobile applications in a tiny, 2mm x 2.2mm, lead-free, 5-pin SC70 package.

Designed to compensate for temperature and process shifts, this power detector reduces output variation to ±0.5dB at full power (5dBm) and to ±1.5dB at low power (-16dBm). This enables fewer end-of-line calibration tests during handset manufacturing.

The MAX2204 uses one of Maxim's state-of-the-art silicon bipolar technologies to achieve this performance, and also operates from 450MHz to 2.5GHz. This performance and flexibility make it ideal for today's demanding closed-loop architecture mobile applications, such as HSDPA/HSUPA, WCDMA, and cdma2000 handset designs.

The MAX2204 features a detection range of -16dBm to +5dBm. It supports both resistive-tapping and directional-coupler architectures. The use of external termination at the input of the device allows a single MAX2204 to be connected to multiple direction couplers.

The MAX2204 is specified over the extended temperature range of -40°C to +85°C. An evaluation kit is available to speed designs. Prices start at $0.39 (10,000-up, FOB USA).

Note :

The MAX2204 is a 450MHz to 2.5GHz linear power detector in a 5-pin SC70 package for mobile applications.

±0.5dB power-detection accuracy ensures excellent performance over temperature.

The MAX2204 builds on the success of Maxim's previous power detector for NCDMA (the MAX2205) by leveraging Maxim's in-house silicon bipolar fabrication technology.

The MAX2204 is ideally suited for mobile applications such as cellular phones and data cards that conform to the demanding HSUPA, HSDPA interface standards, as well as the WCDMA, cdma2000®, and UMTS air interface standards.
