Mitsubishi Electric Develops World’s First GaN HEMT Amplifier Exclusive to Satellite Applications

Product Features

1) GaN HEMT with high output power of up to 100 W (MGFC50G3742S)

To gain 100W output with GaAs amplifiers, it is necessary to combine an additional amplifier with an output of approximately 25 W in the final stage. Mitsubishi Electric’s new GaN HEMT amplifier, the MGFC50G3742S, achieves 100 W output with a single device, while retaining the same size as 25 W GaAs amplifiers, and offering a very high efficiency (power added efficiency) of 60%.

Mitsubishi Electric has also developed GaN HEMT amplifiers with 40 W, 20 W and 2 W outputs, suitable for use in first- and mid-stage amplification. These lower output amplifiers are smaller, lighter and consume less energy.

2) High reliability for satellite applications

Designed for use in satellites, which are usually used for approximately 10 years, Mitsubishi Electric’s GaN HEMTs can operate for as long as one million hours given a chip temperature of 175 degrees C and an operation voltage of 45V, and are fit to operate in severe conditions found in space.
