摘要

We demonstrated a 90-GHz InP-HEMT lossy match amplifier (LMA) with a 20-dB gain for the first time. The power consumption was 220 mW, which is the smallest ever reported for a broadband amplifier with a bandwidth of over 80 GHz. The amplifier acts as a C-R coupled amplifier in the low to medium frequency range and as an L-C match amplifier at high frequencies. This configuration provides both high gain and wide bandwidth. The key to achieving a bandwidth of over 80 GHz is broadband matching in the L-C match amplifier. In this paper, we propose a broadband matching technique with a low-Q network and describe the design guideline we used to get excellent performance.
