Abstract :
High-performance InP/InGaAs double HBTs operating in common-emitter mode with 7.5 W/mm output power density at 10 GHz are reported. A total output power of 600 mW was achieved with five-finger cells having total emitter areas of 176 μm2. Their fT and fmax values are 74 GHz and 89 GHz, respectively. These cells exhibit small-signal maximum stable power gains of 17 dB and Mason´s unilateral power gains of 20 dB at 10 GHz
