Mitsubishi to Launch Ka-band GaN-HEMT MMIC


High output power and low distortion will help downsize satellite earth stations

Mitsubishi Electric has announced a Ka-band (26"“40GHz) 8W GaN HEMT monolithic microwave integrated circuit (MMIC) amplifier for satellite earth stations. The new MGFG5H3001, which is said to offer low distortion and output power rating of 8W, boasts a small footprint that will help to downsize power transmitters.

Ka-band GaN-HEMT MMIC (MGFG5H3001) Satellite networks, which are used for high-speed communication during natural disasters and in areas where ground networks are difficult to construct, are currently implemented mainly in the C-band (4"“8GHz) and Ku-band (12"“18GHz), but higher frequencies are increasingly being used. Also, market demands for deployments in the higher-frequency Ka-band are increasing. Mitsubishi Electric's new Ka-band GaN-HEMT MMIC will help meet the growing demand for higher frequency deployments, as well as facilitate the development of satellite communications equipment capable of extra-high output power and efficiency.

According to Mitsubishi, an optimised transistor configuration delivers industry top-level 8W output power. One chip integrates amplifier transistors circuits, matching circuits and distortion-reducing lineariser. Also, a built-in lineariser achieves low distortion for power transmitters.

Mitsubishi will begin shipping samples on November 1.
