Mitsubishi Electric Corporation 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.
data-transmission capacity
The two GaN HEMT products, one for multi-carrier communications and the other for single-carrier 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.
seven GaN HEMTs
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 the need for increased data transmission capacity.
Until recently, 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.
