MAX2553

Band Class 0, 1, and 10 cdma2000 Femtocell Transceiver

Accelerate Deployment with Worldwide Field-Proven Performance and the Most Compact Radio Design


Please check latest availability status for a specific part variant.

Description

The MAX2553 is a complete single-chip RF-to-bits and bits-to-RF radio transceiver. The device is compliant with the 3GPP2 C.S0010-D femtocell standard for Band Class 0, 1, and 10. It is equipped with multiple receive inputs and transmit outputs for low band, high band, and macrocell monitoring (see Table 1 in the full data sheet).

This fully integrated transceiver facilitates compact radio designs for dongle and stand-alone femtocell products by minimizing external component count. Maxim's MAX-PHY serial interface is used to drastically reduce IC pin count, while worldwide field-proven architecture accelerates time to product deployment.

The MAX2553 features unparalleled receive blocker performance and industry's lowest noise figure for higher data rates and range. Low-power operational modes are available to minimize power consumption. The transmitter is designed to deliver EVM far exceeding the standard requirement at 0dBm.

The MAX2550–MAX2553 is a family of pin-compatible transceivers to cover all major WCDMA and cdma2000® bands. All parts are controlled through a 4-wire interface. The MAX2553 is packaged in a compact 7mm x 7mm TQFN and covers the -40°C to +85°C extended temperature range. A complete radio reference design is available to facilitate custom designs.
