| Summary: | This thesis presents a 2.52 - 2.65 GHz bandpass filter using hairpin resonators in a multilayer configuration for digital broadcasting application. Multilayer configuration technique is used to reduce the size, increase the bandwidth and eventually improve the performance of the filter. A combination of four-pole hairpin resonators was designed using Tchebychev filter with passband ripple of 0.01 dB operating at center frequency of 2.58 GHz with a bandwidth of 130 MHz. The best return and insertion losses in the passband are -27.828 dB and -1.5028 dB, respectively. The circuit was simulated using Computer Simulation Technology (CST). Rogers RO3003 substrate with dielectric constant, Er of 3 and 0.75 mm thickness was used as a material based. The simulated results from the design show that the circuit is working well. Few parameters in the circuit were analysed and have a good relationship to the microwave theory. |
