MGA-43828
925–960 MHz Linear Power Amplifier Module
Data Sheet
Description
The Avago MGA-43828 is a fully matched, highly linear
power amplifier (PA) designed for use in the 925-960
MHz band. Based on Avago’s proprietary 0.25um GaAs E-
pHEMT technology, the device features high linearity, gain
and power-added efficiency (PAE) with integrated power
detector and shutdown functions. The MGA-43828 is ideal
for use as a final stage PA for Small Cell base transceiver
station (BTS) applications.
