The MAX2552 is a complete single-chip RF-to-bits and bits-to-RF radio transceiver. This device is in compliance with the 3GPP TS25.104 femtocell standard for Band III, IV, IX, and X. It is equipped with multiple receive inputs and transmit outputs for low band, high band, and macro- cell monitoring.
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 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 MAX2552/MAX2553 is a family of pin-compatible transceivers that cover all major WCDMA and cdma2000® bands. All parts are controlled by a 4-wire interface. The MAX2552 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.
