Chipset with MAX-PHY Interface Reduces BOM Cost in Femto Base Stations

SUNNYVALE, CA—February 25, 2009—Maxim Integrated Products (NASDAQ: MXIM) introduces the MAX2557/MAX2597, a WCDMA Band II and Band V femto base-station transceiver chipset with a unique digital interface for the North American UMTS market. The receiver (MAX2557) and transmitter (MAX2597) utilize Maxim's proprietary high dynamic range MAX-PHY™ interface to eliminate the need for a mixed-signal analog front-end. The MAX2557 has four low-noise amplifier (LNA) inputs to allow monitoring of WCDMA and GSM macro-network signals. The MAX2599 integrates power amplifiers (PAs) to further reduce BOM expense. This industry-leading chipset is the most integrated and highest performance solution for the burgeoning femto base-station market.

The MAX2557/MAX2597 are the North American versions of Maxim's previously released UMTS Band I solution: the MAX2547/MAX2599 transceiver chipset. The MAX2557 is available in a 48-pin fcLGA package, while the MAX2597 is packaged in a 64-pin fcLGA. Both devices operate over the -40°C to +85°C extended industrial temperature range. Contact the factory for pricing.

For rapid application development, a reference design kit is available, providing a complete evaluation platform and all necessary software. Due to unusually high demand for this product, samples, data sheets, and applications support are available by request only.

Maxim Integrated Products is a publicly traded company that designs, manufactures, and sells high-performance semiconductor products.
