Abstract
RF and Microwave filters can be implemented with transmission lines. Filters are significant RF and Microwave components. Transmission line filters can be easy to implement, depending on the type of transmission line used. The aim of this paper is to develop a set of transmission line filters to do practical work with. There are different transmission lines due to different RF and Microwave applications. The characteristic impedance and how easy it is to incise precise lengths are two important characteristics of transmission lines; thus they are used to investigate which transmission line to use to implement filters. The first part of this paper looks into which transmission line to use to erect a filter. Then the different filter design theories are reviewed. The filter design theory that allows for implementation with transmission lines is used to design the filters. Microstrip transmission lines are used to implement transmission line filters. They are the transmission lines with which it is easiest to change the characteristic impedance. This paper presents a new approach that can be easily involved in the implementation of the radio frequency and microwave (RF/MW) circuits for many applications. The approach is based on the implementation of the system using MATLAB simulink.
