Abstract :
This paper reports results on a transferred-substrate InP heterojunction bipolar-transistor technology for high-frequency power stages. The basic building block is a 2-finger transistor with fT and fmax values of 376 GHz and 385 GHz, respectively, at an emitter size of 0.8 × 5 μm2. The transistors demonstrate more than 7 dB of gain at 96 GHz with good power densities of better than 3.7 mW/μm2. For a 4-finger transistor, fT and fmax reduce to 302/325 GHz while doubling the power. W-band amplifiers based on a single 2-finger transistor have reached a saturated output power of 14.8 dBm at 77 GHz with more than 10 dB return loss on input and output. The results confirm that the transistors are suitable for compact circuit design with minimum inter-stage matching.
