MGA-43328 - 29dBm High Linearity Wireless Data Power Amplifier

General Description

Avago Technologies’ MGA-43328 is a power amplifier for use in the (2.5-2.7)GHz band.

High linear output power at 5V is achieved through the use of Avago Technologies’ proprietary 0.25um GaAs Enhancement-mode pHEMT process.

It is housed in a miniature 5.0mm x 5.0mm x 0.85mm 28-lead QFN package.

Key Features

  •  High gain: 37.3dB.
  •  High linearity performance: 29.3dBm at 5V supply (2.5% EVM, 64-QAM ¾ FEC rate OFDMA, 10MHz bandwidth).
  •  High efficiency: 16.6%.
  •  Built-in detector and shutdown switches.
  •  Switchable gain: 24.5dB attenuation using one single CMOS compatible switch pin.
  •  ETSI spectral mask compliant at 29dBm output power.
  •  GaAs E-pHEMT Technology[1].
  •  Low cost small package size: 5.0 x 5.0 x 0.85 mm3.
  •  MSL-2a and lead-free.
  •  Usable at 3.3V sup.

MGA-43328 (2.5–2.7) GHz 29dBm High Linearity Wireless Data Power Amplifier Data Sheet Description Avago Technologies’ MGA-43328 is a power amplifier for use in the (2.5-2.7)GHz band. High linear output power at 5V is achieved through the use of Avago Technologies’ proprietary 0.25um GaAs Enhancement-mode pHEMT process. It is housed in a miniature 5.0mm x 5.0mm x 0.85mm 28-lead QFN package. It also includes shutdown and switchable gain functions. A detector is also included on-chip. The compact footprint coupled with high gain and high efficiency make the MGA-43328 an ideal choice as a power amplifier for IEEE 802.16 (WiMAX) and WLL applications.
