Maxim Integrated Products has introduced the MAX2557/MAX2597, a W-CDMA 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) uses Maxim's high dynamic range MAX-PHY interface to eliminate the need for a mixed-signal analogue front-end. The MAX2557 has four LNA inputs to allow monitoring of W-CDMA and GSM macro-network signals. The MAX2599 integrates power amplifiers to further reduce BOM expense. This chipset is an integrated and high 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.

For rapid application development, a reference design kit is available, providing a complete evaluation platform and all necessary software.
