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.

Features
• High linearity performance : Max -50dBc ACLR1[1] at 27
dBm linear output power (biased with 5.0V supply)
• High gain : 33 dB
• Good efficiency
• Fully matched
• Built-in detector
• GaAs E-pHEMT Technology[2]
• Low cost small package size: (5.0 x 5.0 x 0.9) mm
• MSL3
• Lead free/Halogen free/RoHS compliance
Specifications
940MHz; 5.0V, Idqtotal =316mA (typ), W-CDMA Test
model #1, 64DPCH downlink signal
• PAE : 14.7%
• 27 dBm linear Pout @ ACLR1 = -50dBc[1]
• 33 dB Gain
• Detector range : 20dB
Applications
• Final stage high linearity amplifier for Picocell and
Enterprise Femtocell PA targeted for small cell BTS
downlink applications.
Note:
1. W-CDMA Test model #1, 64DPCH downlink signal
2. Enhancement mode technology employs positive Vgs, thereby
eliminating the need of negative gate voltage associated with
conventional depletion mode devices.
