Design and Fabrication of Transmission line based Wideband band pass filter

A multi section wideb and band pass filter with a centre frequency of 2.3 GHz and 3-dB bandwidth of approximately 618 MHz, is designed and fabricated. The design of the filter is based on transmission line section based circuit configuration. The salient features of this filter isthat it provides low insertion loss, sharp rejection along with simple approach and easy realization. The designed filter is simulated using Agilent® ADS tool and the experimental characteristics are found to be in close agreement with the simulation.
