Abstract

This paper presents a method to design matching networks using single / double 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. Microstrip line is used when wavelength becomes significantly small compared with the characteristic circuit component length. At microwave frequency, the influence of parasitics in discrete elements becomes more noticeable. This limits their use of in high frequency applications. 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.
