Mitsubishi Expands Satcom GaN HEMT range


13.75 to 14.5 GHz HEMTs are designed for multi- and single-carrier coms, larger data capacity and smaller earth stations

Mitsubishi Electric Corporation has announced t two new 13.75–14.5 GHz (Ku-band) 30W (45.3dBm) GaN HEMTs for SATCOM earth stations. The two products, one for multi-carrier communication and the other for single-carrier communication, will support increased data-transmission capacity and smaller earth stations.

Ku-band satellite systems are increasingly being deployed for emergency communication during natural disasters and for satellite news gathering (SNG) by TV broadcasters in remote areas where cable networks do not exist. Meanwhile, in addition to the growing use of conventional single-carrier communication, multi-carrier communication is increasingly needed for fast, high-volume communication and to support the downsizing of mobile stations for purposes such as SNG.

So far, Mitsubishi Electric has introduced five GaN HEMTs for multi-carrier and single-carrier SATCOM earth stations. The two new 30W GaN HEMTs will enable more flexible amplifier designs, including for rated power levels and the use of GaN drivers. They also will support the downsizing of earth stations as well as faster, larger-capacity satellite communication.
