Abstract

As frequency increasing and correspondingly reduced wavelength, the influence of parasitics in discrete elements becomes more noticeable. This limits their use of in high frequency applications. As an alternative to lumped elements, distributed components are widely used when wavelength becomes significantly small compared with the characteristic circuit component length. Therefore, this paper presents a method to design matching networks using single stub microstrip line for input and output port of microwave LNA in a prescribed frequency band with requirements about the transducer gain flatness is presented. The superior performance characteristics of the microstrip line make it one of the most important medium of transmission in microwave transistor amplifiers in the microwave integrated-circuit technology. Matlab programming is used to obtain the Smith chart results for input and output microstrip line matching networks.
