Abstract :
Reported is the first experimental microwave noise characterisation of 0.9 times 11.5 mum2 emitter AlInAs/GaAsSb/InP double heterojunction bipolar transistors with a `type-I` AlInAs emitter. The devices feature cutoff frequencies of f T = 210 GHz and f MAX = 127 GHz, and achieve a minimum noise figure NF min < 3 dB with an associated gain G A = 12 dB at 10 GHz.
