MAX2551
Band II and V WCDMA Femtocell Transceiver with
GSM Monitoring
Accelerate Deployment with Worldwide Field-Proven Performance and the Most
Compact Radio Design
Overview
Description
The MAX2551 is a complete single-chip RF-to-bits and bits-to-RF radio transceiver. The
device is in compliance with the 3GPP TS25.104 femtocell standard for Band II and V. It's
equipped with multiple receive inputs and transmit outputs for low band, high band, and
macro-cell monitoring (Table 1 in the full data sheet).
This fully integrated transceiver facilitates compact radio designs for dongle and
standalone femtocell products by minimizing external component count. Maxim's MAXPHY serial interface is used to drastically reduce IC pin count, while worldwide field-proven
architecture accelerates time to product deployment.
The device features unparalleled receive blocker performance and the 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 by a 4-wire interface.
The MAX2551 is packaged in a compact 7mm x 7mm TQFN and specified over the -40°C
to +85°C extended temperature range. A complete radio reference design is available to
facilitate custom designs.
