摘要
A 0.15 mum T-gate AlGaN/GaN-HEMT 2-inch technology has been developed. Transistors with 120 mum gatewidth show a peak transconductance of 300 mS/mm and cut-off frequencies f(t) and f(max). of 65 GHz and 149 GHz, respectively. Large periphery 720 pin gatewidth devices are capable of CW operation up to 40 GHz yielding an output power of 0.91 W and a linear gain of 6 dB at 35 GHz To the authors' knowledge these results represent the highest absolute power level so far achieved with a GaN-HEMT in the K-a-band.
