GaN HEMT Amplifier delivers World’s Highest PAE of 67% allowing the replacement of bulky TWTAs
Mitsubishi Electric is introducing an internally matched GaN HEMT power amplifier for C-band satellite communication, which offers a power-added efficiency (PAE) of 67%. This is the world’s highest PAE rating as it is more than seven points higher than the rating of conventional C-band GaN amplifiers.
MitsMeasuring just 17.4mm x 24.0mm x 4.3mm and with a mass of only 7.1g Mitsubishi Electric’s new GaN HEMT will allow for the design of smaller and lighter transmitter devices helping microwave communication satellites to save power. This new semiconductor will accelerate the replacement of the currently-used traveling wave tube amplifiers (TWTAs) with GaN HEMT semiconductor amplifiers resulting in significantly smaller, lighter and more efficient satellite transponders.
