摘要:
The first high power demonstration of an InGaP/GaAs heterojunction bipolar transistor is presented. Multifinger selfaligned HBTs were tested at 3 GHz. A maximum Output power of 2.82 W CW was obtained for a 600 mum2 emitter area device (4.7 mW/mum2 power density) with an attendant gain of 6.92 dB; simultaneously, the device exhibited 55.2% power added efficiency, 69.1% collector efficiency and 8.0 x 10(4) A/cm2 emitter current density.
