New UMTS femto base-station transceiver chipset

Maxim Integrated Products introduced 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 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. The MAX2557/MAX2597 are the north American versions of Maxim's previously released UMTS Band I solution: the MAX2547/MAX2599 transceiver chipset. Both devices operate over the -40°C to +85°C industrial temperature range.

Package:
1. The MAX2557 is available in a 48-pin fcLGA package
2. The MAX2597 is packaged in a 64-pin fcLGA.

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