GaN power amplifier module for 5G massive MIMO base stations (MGFS48G38MB)

GaN power amplifier module for 5G massive MIMO base stations (MGFS48G38MB)

TOKYO, September 14, 2023 - Mitsubishi Electric Corporation (TOKYO: 6503) announced today that it will begin shipping samples of a new Gallium Nitride (GaN) power amplifier module for use in 5G massive MIMO1 (mMIMO) base stations on September 21. Power amplifier modules help reduce the power consumption of 5G mMIMO base stations.

Providing high-speed, large-capacity communications, 5G mobile networks are becoming increasingly popular across the world, with their 5G mMIMO base stations installed predominantly in metropolitan areas. Since these base stations utilize multi-element antennas and a correspondingly high number of power amplifiers, highly efficient power amplifier modules play an important role reducing the power consumption and manufacturing costs of these base stations. In addition, the power amplifier module needs to deliver 3GPP-compliant low distortion characteristics2 over a wide frequency range in order to be compatible with multiple countries' networks.

Mitsubishi Electric will commence sample shipments of a GaN power amplifier module for 5G mMIMO base stations that can deliver an average output power of 8W (39 dBm) over wide frequencies ranging from 3.4GHz to 3.8GHz. In particular, the product is suitable for 64T64R mMIMO antennas3 because of its more than 43% high power-added efficiency operation. The high efficiency and low distortion result from Mitsubishi Electric's new GaN High Electron Mobility Transistors (HEMTs). The wideband characteristics in addition to the high efficiency are realized using the company's original circuit design and high-density packaging techniques.


  1. 1Multiple Input Multiple Output is a wireless communication technique that improves communication speed and quality. MIMO uses multiple antennas at both the transmitter and receiver end
  2. 2In 5G mobile networks, in-band and out-of-band distortion characteristics are regulated by the Third Generation Partnership Project (3GPP)
  3. 364T64R is a massive MIMO antenna consisting of 64 transmitters/receivers. In mMIMO installations, there is a 32T32R antenna using 32 transmitters/receivers
