Bersant Gashi,Laurenz John,Dominik Meier,Markus Rosch,Axel Tessmann,Arnulf Leuther,Hermann Massler,Michael Schlechtweg,Oliver Ambacher +8 more
TL;DR: In this paper, the design and performance of a medium-power amplifier (MPA) sub-millimeter-wave monolithic integrated circuit (S-MMIC) is presented, which demonstrates a flat small-signal gain of approximately 20 dB, measured over a frequency span from 290 to 410 GHz, and a respective 3-dB bandwidth from 280 to 430 GHz.
