Abstract

Up to now the simplified real-frequency technique has been applied to the design of broadband multistage microwave amplifiers where gain and voltage standing wave ratio (VSWR) are optimized. In this work, the method is extended to the optimization of the noise figure in parallel with the gain and VSWR. The synthesis of the networks is carried out in two ways, with lumped elements and distributed elements. An ultrawideband GaAs monolithic amplifier, a transimpedance amplifier for optical receivers, and a low-noise ultrawideband amplifier are described as examples of design.<>
