SUNNYVALE, CA—February 10, 2010—Maxim Integrated Products (NASDAQ: MXIM) announces the MAX2203 RMS power detector. Designed to operate from 800MHz to 2.0GHz, the MAX2203 accepts an RF signal at the input, and outputs the same voltage regardless of the peak-average of the input signal. This RMS power detector is ideal for WCDMA (wideband code-division multiple access), cdma2000®, and HSDPA/HSUPA (high-speed downlink/uplink packet access). Using Maxim's expertise with the SiGe BiCMOS process and wafer-level packaging technology, the MAX2203 offers a repeatable and exceptionally accurate RMS output over temperature and modulation. This "future-proof" performance means that the MAX2203 is modulation independent. A circuit can now be reused with no additional engineering effort in new end-equipment designs that add modulation schemes.

The output voltage and input power is linear in dB. The device has a -25dBm to +3dBm detection range, and every dB change in input power gives 40mV typical change in output voltage. Boasting 0.1dB typical RMS accuracy from WCDMA modulation change and ±0.5dB detection error due to temperature, the MAX2203 improves closed-loop performance of the transmit path in today's multiband, multimode smartphones, cellular phones, broadband laptop data cards. It can also be used for SAR limiting.

The MAX2203EWT+T operates from a 2.5V to 4.2V supply. Fully specified over the -40°C to +85°C extended temperature range, it is available in an ultra-small, 6-pin WLP. Prices start at $0.50 (1000-up, FOB USA).

Maxim Integrated Products is a publicly traded company that designs, manufactures, and sells high-performance semiconductor products. The Company was founded over 25 years ago with the mission to deliver innovative analog and mixed-signal engineering solutions that add value to its customers' products. To date, it has developed over 6200 products serving the industrial, communications, consumer, and computing markets.

Maxim reported revenue in excess of $1.6 billion for fiscal 2009. A Fortune 1000 company, Maxim is included in the Nasdaq 100, the Russell 1000, and the MSCI USA indices. For more information, go to www.maxim-ic.com.
