Product Releases
Mitsubishi Electric Corporation announced it has developed two Gallium Nitride (GaN) High-Electron Mobility Transistor (HEMT) C-band (4–8GHz) amplifiers for satellite earth stations. The MGFC50G5867 and MGFC47G5867, featuring power outputs of an industry-leading 100W and 50W, respectively, will ship on a sample basis beginning January 10, 2012.
Gallium Arsenide (GaAs) amplifiers have been commonly employed in microwave power transmitters. In recent years, however, Gallium Nitride (GaN) amplifiers have become increasingly popular due to their high breakdown-voltage and power density, high saturated electron speed and ability to contribute to power saving and the downsizing of power transmitter equipment.
High output power, efficiency and high-voltage operation
- 100 W or 50 W output power
- More than 43% of power added efficiency
- 40 V high-voltage operation
Low Distortion
- Output power meeting 3rd-order Inter Modulation (IM3) = -25dBc of 46dBm
- Internally impedance- matched
