A 9.5–10.5GHz 60W AlGaN/GaN HEMT for X-band high power application

In this paper, we report our result of a 60W AlGaN/GaN HEMT with the operating frequency in X-band. The device technology is extension of well-established Eudyna commercial L-/S-band AlGaN/GaN HEMT technology. The device shows output power of over 60W and a high linear gain of 9.6dB in wide frequency range of 9.5-10.5GHz, operating at 40 V drain bias voltage with the pulsed conditions at a duty of 10% with a pulse width of 100 musec. The results show the developed 60W AlGaN/GaN HEMT has high power capability covering practical frequency range for X-band high power applications with proven device technology.
