The development of microwave range filter play important role in many RF or microwave applications. Filters are two port networks used to control the frequency response in an RF or microwave system by allowing transmission at frequencies within the passband of the filter, and attenuation within stopband of the filter. This research project consist of the elementary principle of microwave theory, the elementary knowledge of microwave filter design as well as fabrication and performance evaluation of Chebychev bandpass filters. The purpose of the research project is to compare the compatible microstrip filters design and the material used in the layout designs in order to get the better performance of the filter. The insertion loss method was used to produce the parallel coupled quarter wavelength resonator filters. The compatible filter mentioned in this project able to filter out the required frequency for Digital Radio Broadcasting in the range of 1.452 GHz to 1.492 GHz. The designs were implemented using development simulation software Microwave Office 2003 (V6.01). Different prototypes of Chebychev bandpass hairpin line filters were designed. The filters were fabricated on the two different types of substrate material, which is FR4 epoxy glass and the ROGER4003C material. The entire filters design and the performances of the substrate materials to the designs are contrast. The bandwidth for FR4 hairpin filter design differs from that of the ROGER4003C design.. In term of scattering parameters for Sll and S22, the ROGER4003C microstrip filter design shows low loss condition compared with FR4 filter design results. The research shows that ROGER4003C has produced better performance for the microstrip filter design
