TOKYO, June 8, 2023 - Mitsubishi Electric Corporation (TOKYO: 6503) announced today it has developed what is believed to be the world's first^* gallium nitride (GaN) power amplifier that achieves a frequency range of 3,400MHz using a single power amplifier, which the company has demonstrated can be used for 4G, 5G and Beyond 5G/6G communication systems operating at different frequencies in a single base station. The amplifier is expected to enable the radio unit (transceiver) to be shared for different communication systems and lead to more power-efficient base stations. Technical details will be presented at the IEEE International Microwave Symposium 2023 this month.
