Mitsubishi Electric to Expand Range of Ku-band GaN-HEMT Lineup
Mitsubishi Electric Corporation has announced that two new 12.75-13.25 GHz (Low-Ku band) 70W (48.3dBm) gallium-nitride high-electron-mobility transistors (GaN HEMTs) will be added to the company's GaN HEMT lineup for satellite-communication (SATCOM) earth stations.

The two GaN HEMT products, one for multi-carrier1 communications and the other for single-carrier2 communications, support increased data-transmission capacity and smaller earth stations even in the Low-Ku band. The two products will be launched on January 15, 2023.
Ku-band satellite communication systems are increasingly being deployed for emergency communications during natural disasters as well as for satellite news gathering (SNG) by TV broadcasters in rural areas where fiber and/or cable networks are not available. For SATCOM earth stations, current mainstream systems use a 14 GHz band, but in the near future they are expected to use the Low-Ku (13 GHz) band as well as the Ka (28 GHz) band to address needs for increased data-transmission capacity.
Until now, Mitsubishi Electric has offered a lineup of seven GaN HEMTs for multi-carrier and single-carrier SATCOM earth stations. The two new 70W GaN HEMTs now being introduced will also support emergency communications and SNG in the Low-Ku band.
Product Features
1. Expanded GaN HEMT lineup will support spread of SATCOM-based emergency systems and SNGs
The additional two 70W GaN HEMTs will facilitate various kinds of satellite communications in the Low- Ku band envisioned in the near future.
2. Adopt same small package used for 14 GHz band
Both two products deliver output power as high as 70W, which will help to downsize earth stations.
3. Maintain low IMD3 even at wide offset frequencies of up to 400MHz
The MGFK48G2732A for multi-carrier communications delivers IMD33 of less than -25dBc at wide offset frequencies4 of up to 400MHz, thereby addressing multi-carrier communication requirements.
Future Developments
In addition to the 14GHz band, Mitsubishi Electric will expand its low-Ku band product lineup to contribute to the further downsizing of satellite-communication earth stations.
