Order-of-magnitude improvement in power capacity was achieved in single-finger heterojunction bipolar transistors with sub-mus pulses and less than 1% duty cycle, thereby approaching isothermal operation. At 6 GHz, the output power capacity was 14 mw/mum2, which was much higher than the common benchmark of 1 mw/mum2. The improvement in power capacity was… CONTINUE READING
