Mitsubishi Electric Corporation has announced that they will expand their lineup of Gallium Nitride High Electron Mobility Transistors (GaN-HEMTs) to include units with an output power of 100 W and 70 W for use in satellite earth stations utilizing the Ku-band. According to Mitsubishi Electric’s research (as of September 27), the new 100 W GaN-HEMT offers an output power that is among the highest currently available in the Ku Band. They 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 their Ku-band GaN-HEMT lineup to meet this growing demand for higher output power levels with the introduction of MGFK50G3745 model, boasting an output power of 100 W, and the 70 W output power MGFK48G3745 model. The products feature:
1) Industry-leading output power contributes to miniaturization
- Transistor structure optimization, with the MGFK50G3745 model delivering an output of 100W, ideal for satellite earth stations utilizing the Ku-band
- GaN-HEMTs with fewer parts, thereby contributing to the miniaturization of transmitter equipment in satellite earth stations
2) Expands product line-up and meets diverse needs
- New 100 W and 70 W models, addressing the need for more diverse output power ratings of transmitter equipment for satellite earth stations
- Individual transmitter components can be configured independently during manufacture, eliminating the need for on-site configuration and shortening overall development times
- Utilizes the existing MGFG5H1503 power amplifier as a driver stage, leveraging the latter’s linearizer device to help reduce distortion in power transmitters
