Japan, June 12 -- Mitsubishi Electric Corporation announced that it has developed a world's first1 compact 7GHz band gallium nitride (GaN) power amplifier module (PAM) with the world's highest1 power efficiency, which is expected to enhance the ease of installation as well as the power efficiency of 5G-Advanced base stations and thereby support the transition to 6G. Mitsubishi Electric successfully verified its new PAM's performance in a demonstration using 5G-Advanced communication signals for the first time in the world.Mitsubishi Electric developed its 7GHz GaN PAM using proprietary matching-circuit technology and high-performance GaN transistors. The compact module measures only 12.0mm x 8.0mm (prototype) thanks to the high-density moun...
