Abstract:
A bandpass filter comprises a first capacitor, a second capacitor, a third capacitor and at least two resonators. The first and second capacitors are coupled in parallel with each other, and each of the first and second capacitors includes an input. The third capacitor is coupled between the first capacitor and the second capacitor at their respective inputs. The at least two resonators are coupled in parallel with the first capacitor and the second capacitor and are positioned adjacent to each other at a distance such that the at least one component of the resonators are electromagnetically coupled together to provide three (3) transmission zeros.
