| Abstract(in English) | We demonstrated a 90-GHz InP-HEMT lossy match amplifier (LMA) with a 20-dB gain for the first time. We obtained this performance with the power consumption of 220 mW, which is the smallest one ever reported for an over 80-GHz broadband amplifier. The amplifier acts as a C-R coupled amplifier in the low to medium frequency range and as an L-C match amplifier at the high frequencies. Therefore, this configuration provides both high gain and wide bandwidth. The key to achieve a 90-GHz bandwidth 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 for the excellent performance. |
