Abstract:

In this paper, the design and characterization of a single-stage amplifier based on InP/InGaAs/InP double heterojunction bipolar transistors (DHBT) in transferred - substrate technology is reported. The two fingers amplifier,with a total area of 2×0.8×5 µm2 and an ft and fmax of 383 and 370 GHz, respectively, exhibits a small signal gain of 8 dB at 90 GHz.
