Design of a broadband microwave amplifier constructed with mixed lumped and distributed elements for mobile communication

In this paper, we designed a broadband microwave amplifier utilizing a "semi-analytic method to describe symmetrical lossless two-ports with two kinds of elements", namely, distributed and lumped elements in cascade connection. It is expected that the results presented in this paper will find immediate application to design analog/digital mobile communication systems on MMIC or VLSI chips.
