MGA-43428
High Linearity 851 – 894 MHz Power Amplifier Module
Data Sheet
Description
Avago Technologies’ MGA-43428 is a fully matched
power amplifier for use in the (851-894) MHz band. High
linear output power at 5V is achieved through the use of
Avago Technologies’ proprietary 0.25um GaAs Enhance-
ment-mode pHEMT process. MGA-43428 is housed in a
miniature 5.0mm x 5.0mm molded-chip-on-board (MCOB)
module package. A detector is also included on-chip. The
compact footprint coupled with high gain, high linearity
and good efficiency makes the MGA-43428 an ideal choice
as a power amplifier for small cell BTS PA applications.
Applications
• Final stage high linearity amplifier for Picocell and
Enterprise Femtocell PA targeted for small cell BTS
downlink applications.
