35% PAE 6 W Ku-band power amplifier module

Power amplifiers with 6 W output power in Ku- and X-band are demonstrated. The amplifier is a miniaturized hybrid module consisting of an MMIC and an internally matched FET which employs a DH-HEMT device technology. The amplifiers have exhibited PAEs of 35% and 45% in Ku and X bands.
