PRODUCT DESCRIPTION
The AWB7228 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 LTE,WCDMA and HSDPA air interfaces
operating in the 2.545 GHz to 2.69 GHz band, the
AWB7228 delivers up to +27 dBm of LTE (E-TM1.1)
power with an ACPR of -47 dBc. It operates from
a convenient +4.5 V supply and provides 27 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.

(4) Use only VCC2 (pin 11) current when calculating device junction temperature.
(5) Rise Time defined from time at which VREF is switched from 0 V to +2.85 V, to time at which the RF output power
achieves 90% of the average steady-state “on” level; Fall Time defined from time at which VREF is switched from +2.85 V
to 0 V, to time at which the RF output power decreases to 10% of the average steady-state “on” level.

Note:
To achieve the RF Switching Time specifications listed in Table 4 the maximum recommended
capacitance on the VREF line is 0.01µF. The noise on the VREF line should be kept as low as
possible to minimize required capacitance.
