MGA-43728
2.62–2.69 GHz Linear Power Amplifier Module
Data Sheet
Description
The Avago MGA-43728 is a fully matched, highly linear
power amplifier (PA) designed for use in the 2.62–2.69
GHz 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-43728 is ideal
for use as a final stage PA for Small Cell base transceiver
station (BTS) applications.

Applications
•
Final stage high linearity amplifier for Picocell and
Enterprise Femtocell PA targeted for small cell BTS
downlink applications.
Note:
1. LTE 10MHz 50 RB Test Mode 1.1 downlink signal.
2. Enhancement mode technology employs positive V
GS
, thereby
eliminating the need of negative gate voltage associated with
conventional depletion mode devices.
