Abstract

An InP/InGaAs/InP double heterojunction bipolar transistor was fabricated and its Ka-band power performance characterized. The device employed a 30 nm highly doped InGaAs base, and a 150 nm collector with an InAlGaAs linearly graded at the base-collector junction to prevent current blocking and maintain breakdown voltage. The dc current gain is 28.4 at a current density of J_C = 666 kA/cm² and the breakdown voltage (BV_CEO) is larger than 5 V. A submicrometer InP/InGaAs DHBT with an emitter size of 0.6 × 12 μm² demonstrated a maximum cutoff frequency (f_T) of 230 GHz, and a maximum output power density of 3.7 mW/μm² at 29 GHz.
