Mitsubishi adds 100W and 70W Ku-band GaN-HEMTs
Mitsubishi Electric is expanding its lineup of GaN-HEMTs to include units with 100W and 70W output power for use in satellite earth stations using the Ku-band (12-18GHz).
The new 100W GaN-HEMT has an output power that is among the highest currently available, according to Mitsubishi Electric's own research as of September 27.
It will begin shipping samples on October 1.
The demand for satellite communication is increasing, especially in Ku-band, which enables high-speed communication even under adverse conditions, such as natural disasters, and in areas where construction of communication facilities is difficult. The deployment of transmitter equipment using higher-power GaN-HEMTs has become more common in recent years, particularly in high-speed applications such as satellite news gathering.
Mitsubishi Electric is expanding its Ku-band GaN-HEMT lineup to meet this growing demand for higher output power levels with the introduction of its MGFK50G3745 model, boasting an industry-leading output power of 100W, and the 70W output power MGFK48G3745 model.
The company has optimised the transistor structure to produce these high output powers, and is using the existing MGFG5H1503 power amplifier as a driver stage, making use of the latter's linearizer device to help reduce distortion in power transmitters.
Individual transmitter components can be configured independently during manufacture, eliminating the need for on-site configuration and shortening overall development times, according to Mitsubishi.
