Abstract
The authors have simultaneously demonstrated 10 W output power, 13.5 dB gain and 63% power-added efficiency on a single 16.8 mm pseudomorphic high electron mobility transistor (PHEMT) device at 2.45 GHz. This result represents the highest output power from a single transistor at S-band frequencies. The power density exhibited by the PHEMT device was 625 mW/mm which is significantly higher than a typical MESFET power density of 400 mW/mm.<>
