AWB7221 2.30 GHz to 2.70 GHz Small-Cell Power Amplifier Module PRELIMINARY DATA SHEET - Rev 1.1 FEATURES • InGaP HBT Technology • 2.5% EVM @ +28 dBm (OFDMA) • 31 dB Gain • Integrated Step Attenuator • Integrated Output Power Detector • High Efficiency • Low Transistor Junction Temperature • Matched for a 50 Ω System • Low Profile Miniature Surface Mount Package; RoHS Compliant APPLICATIONS M52 Package 14 Pin 7 mm x 7 mm x 1.3 mm Surface Mount Module • WiMAX and LTE Air Interfaces • Picocell, Femtocell, Home Nodes • Customer Premises Equipment (CPE) • Data Cards and Terminals PRODUCT DESCRIPTION The AWB7221 is a fully matched, Multi-Chip-Module (MCM) designed for picocell, femtocell, and customer premises equipment (CPE) applications. Its high linearity and efficiency meet the extremely demanding needs of small cell infrastructure architectures. Designed for WiMAX and LTE air interfaces operating in the 2.30 GHz to 2.70 GHz band, the AWB7221 delivers up to +28 dBm of WiMAX power with exceptionally low EVM. It operates from a convenient +4.2 V supply and provides more than 30 dB of gain. The device is manufactured using an advanced InGaP HBT MMIC technology offering state-of-theart reliability, temperature stability, and ruggedness. The self-contained 7 mm x 7 mm x 1.3 mm surface mount package incorporates RF matching networks optimized for output power, efficiency, and linearity in a 50 Ω system.
