MAX2552
Band III, IV, IX, and X WCDMA Femtocell
Transceiver with GSM Monitoring
General Description
Features
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 mac-
ro-cell monitoring (Table 1).

S WCDMA/HSPA+ Band III, IV, IX, and X Operation
S TS25.104 Standard Compliant
S Multiple LNA Inputs for WCDMA, PCS, and GSM
Macrocell Monitoring (Bands II, III, IV, V, IX, and X)
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 acceler-
ates time to product deployment.
S High Level of Integration
On-Chip Fractional-N Frequency Synthesizers
for LO Generation
No Tx SAW Filters Required
Integrated PA Drivers for Lower-Cost Power
Amplifier Designs
12-Bit AFC DAC to Control TCXO
On-Chip Temperature Sensor
Three General-Purpose Outputs
Reference Clock with Selectable CMOS and Low
Swing Output
The device features unparalleled receive blocker perfor-
mance and the industry’s lowest noise figure for higher
data rates and range. Low-power operational modes are
available to minimize power consumption. The transmit-
ter is designed to deliver EVM far exceeding the stand-
ard requirement at 0dBm.
PLL Lock-Detect Output Through GPO3
S Optimized Receiver Performance
Exceptional Receive Sensitivity
High Dynamic Range Sigma-Delta ADCs Allow
Simple AGC Implementation with Switched Gain
States
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.
