High Linearity 851-894 MHz Power Amplifier Module

Currently Viewing:

The Broadcom 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 Broadcom's proprietary 0.25um GaAs Enhancement-mode pHEMT process.

A detector is also included on-chip.


  • High Gain: 34dB
  • High Linearity performance: Max -50dBc ACLR at 27.2dBm linear output power
  • Good efficiency
  • Fully matched
  • Built-in detector
  • GaAs E-pHEMT Technology
  • MSL3


  • Final stage high linearity amplifier for Picocell and Enterprise Femtocell PA targeted for small cell BTS downlink applications.
