Mitsubishi Electric to Ship Samples of 3.6-4.0GHz, 16W GaN Power Amplifier Module for 5G Massive MIMO Base Stations

Mitsubishi Electric Corporation (TOKYO: 6503) announced today that it will begin shipping samples of a new 16W-average-power gallium nitride (GaN) power amplifier module (PAM) for 5G massive MIMO (mMIMO) base stations on March 25. This PAM product, which operates in the 3.6-4.0GHz band, can be widely deployed in North America and East and Southeast Asia. As 5G networks expand from urban centers to regional areas, mMIMO base stations, especially 32T32R mMIMO base stations, are expected to be increasingly deployed. Mitsubishi Electric’s 16W GaN PAM is particularly well suited for 32T32R mMIMO base stations because it reduces both production costs and power consumption.

Since mMIMO base stations use multi-element antennas and many power amplifiers, there is a growing need for highly efficient power amplifiers to help reduce base station production costs and power consumption. In particular, PAMs strongly contribute to lower production costs because they are easy to mount on a printed circuit board, unlike discrete power amplifiers that need many on-board components. While power amplifiers are required to deliver low-distortion characteristics compliant with 5G signal quality, they must also support different frequency bands in various countries and additionally must achieve increasingly higher output power to support longer communication distances as 5G networks expand from urban areas to surrounding cities.
