Abstract

This article reports on the ﬁrst demonstration of distributed ampliﬁer monolithic microwave integrated circuits (MMICs) with a bandwidth (BW) of more than 300 GHz. The three presented circuits utilize a uniform traveling-wave ampliﬁer topology with six, eight, and ten unit cells, respectively. In this article, the impact of the connection between the gate line and the transistors on the achievable performance is investigated. It is demonstrated that a short connection clearly provides a more fav
