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-the-
art 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.
