PRODUCT DESCRIPTION
The AWB7122 is a highly linear, fully matched, power
amplifier module designed for picocell, femtocell, and
customer premises equipment (CPE) applications.
Its high power efficiency and low adjacent channel
power levels meet the extremely demanding needs
of small cell infrastructure architectures. Designed
for LTE, WCDMA, HSDPA air interfaces operating
in the 1805 MHz to 1880 MHz band, the AWB7122
delivers up to +24.5 dBm of LTE (E-TM1.1) power with
Su p p ly
Vo lta g e
an ACPR of -47 dBc. It operates from a convenient
+4.2 V supply and provides 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.

Notes:
1. 10uF and 100uF capacitors are optional.
2. Applications that have large supply voltage transients may benefit from the
use of TVS diodes. For such applications, recommended TVS diodes are
SM05T1G or SMJ5.0A.
