Abstract
A band pass hairpin filter that has improved pass band performance and low loss. The filter has a dielectric substrate. The dielectric substrate has a top and bottom surface. A hairpin resonator is mounted to the top surface. The resonator has an open end and a closed end. An input coupling element is located adjacent to and is communicated with the resonator. An output coupling element is located adjacent to and is communicated with the resonator. A first inductive element is connected to the resonator. A second inductive element is connected to the input coupling element. A third inductive element is connected to the output coupling element.
