Abstract

This project presents the minimization of Chebyshev 9th order band pass filter with a center frequency of 5.75GHz and a bandwidth of 100MHz. The minimization of the band pass filter has taken considerations on the same design specifications and performances. This thesis will compare the simulation results of two substrates, TLY-5A and FR4. The designed circuits were simulated using An-soft SV software. The fabrication of the miniaturized band pass filter was realized using the FR4 dielectric substance by using parallel coupled method. The minimized filters were named as Ω-Type and W-Type. The insertion loss of the Ω-Type filter was – 20.01 dB with a bandwidth of 460 MHz operating at 5.75 GHz. The W-Type had an insertion loss of -23.03 dB with a bandwidth of 260 MHz operating at 5.75 GHz. With this research, smaller band pass filter can be used in applications such as RF front end receiver and other communication systems in the future.
