Demonstration of a Sub-Millimeter Wave Integrated Circuit (S-MMIC) using InP HEMT with a 35-nm Gate
In this paper, we present two single stage MMIC amplifiers with the first demonstrating a measured S21 gain of 3-dB at 280-GHz and the second demonstrating 2.5-dB gain at 300- GHz, which is the threshold of the sub-millimeter wave regime. The high-frequency operation is enabled by a high-speed InP HEMT with a 35-nm gate. This is the first demonstrated S21 gain at sub-millimeter wave frequencies in a MMIC.
