Mitsubishi Electric Announces Sale of Ku Band Low Noise GaAs HEMT.

TOKYO -- Mitsubishi Electric  Corporation (TOKYO:6503) (President and CEO: Setsuhiro Shimomura) announced today it has finished development of a Ku band1 low noise GaAs High Electron Mobility Transistor (HEMT) used in low noise amplifiers for 10-12 GHz Direct Broadcast Satellite (DBS) and Very Small Aperture Terminal (VSAT) reception systems. Sample shipments will begin on February 15, 2007.

Aim of Sale

Satellites that use wireless communication systems can build a much larger service area network compared to fiber optic cable communication systems, etc. It is expected to be quickly adopted by countries experiencing economic high-speed growth and developing communication infrastructure, in particular China, which has launched its first communications satellite in October of this year with a second satellite launch planned for 2007, and is expected to greatly increase demand in preparation for the 2008 Olympics in Beijing.

The HEMT we have developed is a transistor used in first stage low-noise amplifiers for down converters in receiver systems that convert 12 GHz band electrical waves sent from broadcast and/or communications satellites into intermediate frequencies in the 1-2 GHz band. In addition to using the industry-standard Micro X Type26 in the package for easy mounting to a substrate, the device has enhanced noise characteristics which contribute to the improved productivity and functionality of satellite communications equipment.

Product Features

1. Micro x standard package

Using the micro X type standard for the package, it is easier to mount it to the motherboard, improving satellite communication device productivity. Adding the previous small footprint leadless type, customers can choose between two types to meet their needs.

2. 0.05dB improved noise factor

An improved surface treatment process improves noise factor, a measurement of feedback emitted from a device, by 0.05dB3 compared to previous models4 to 0.35dB.
