2.3-2.5 GHz 29dBm High Linearity Wireless Data Power Amplifier

Currently Viewing:

The Broadcom MGA-43228 is a power amplifier for use in the (2.3-2.5)GHz band. High linear output power at 5V is achieved through the use of Broadcom's proprietary 0.25um GaAs Enhancement-mode pHEMT process.

It also includes shutdown and switchable gain functions.


  • High Gain: 38.5dB
  • High Linearity performance: 29.2dBm at 5V supply
  • High efficiency: 16.1%
  • Built-in detector and shutdown switches
  • GaAs E-pHEMT Technology
  • MSL-2a and lead-free
  • Usable at 3.3V supply for lower supply voltage applications


  • High linearity amplifier for IEEE 802.16 fixed terminal amplifier
  • WLL amplifier
