Abstract :
High power density and high-efficiency AlGaInP/GaAs power HBT´s have been successfully designed and fabricated by using 14 double-fingers emitters in parallel and related input and output matched circuits. Device material structure and layout design are discussed and optimized in detail. Output power of 1 W (power density of 2 mw/μm 2) with power-added efficiency of 64% at 2 GHz has been achieved
