On the investigation of voltage standing wave ratio to design a low noise wideband microwave amplifier

In this paper, a new trend in the design of a microwave amplifier is proposed. The pivot element in the design is to numerically investigate the the relation between VSWR with different frequencies, reflection coefficients, and noise figures. Multiple curves relating the VSWR with both the reflection coefficient and the transducer gain facilitates the location of a starting point for the optimization process involved in the design of microwave amplifiers. The designs obtained by the proposed procedure proved to be accurate and simple.
