Abstract
This paper presents a novel trisection wideband bandpass filter which is centered at 3.6 GHz with 50% fractional band width. The design process of this filter is based on frequency dependent coupling matrix. The frequency dependent coupling is introduced to the filter by separate electromagnetic coupling paths. Two transmission zeros are achieved near the passband. Another transmission zero is generated by harmonic effect. These transmission zeros together improve the selectivity of the filter. The filter was manufactured and measured. Measurements are in good agreement with the simulations.
