Popis: Gallium nitride transistors for high power microwave application are often limited by power loss due to extended transistor finger size. A new design for the gate supply is presented which allows for higher power gain compared to conventional transistor designs. Using this technique a linear gain of 20 dB is measured for a packaged power device delivering 28 Watt at 2GHz
