摘要

本文提出了一种在规定频带内用单/双短线微带线设计微波LNA输入输出端口匹配网络的方法，并对换能器增益平坦度提出了要求。当波长与特征电路元件长度相比明显变小时，使用微带线。在微波频率下，离散元件寄生效应的影响更为明显。这限制了它们在高频应用中的使用。微带线优越的性能特点使其成为微波集成电路技术中微波晶体管放大器中最重要的传输介质之一。利用Matlab编程得到输入输出微带线匹配网络的史密斯图结果。

Graphical analysis of microstrip line matching network for 2.4 GHz microwave LNA via matlab coding

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.
