Abstract
A filter including at least two resonator through-holes defining apertures in the top surface surrounded by respective plates which in combination with the through-holes associated therewith define primary and secondary shunt zeros adapted to provide low ripple and high rejection adjacent the bandpass. In the embodiment shown, the through-hole of the primary shunt zero is directly capacitively or inductively coupled to an input/output pad, while the through-hole of the secondary shunt zero is indirectly capacitively or inductively coupled to the input/output pad via a coupling bar extending between the input/output pad and the secondary shunt zero. In another embodiment, the secondary shunt zero may be capacitively or inductively coupled directly to the input/output pad. In still a further embodiment, more than two of the resonator through-holes in combination with respective plates associated therewith define additional shunt zeros capacitively or inductively coupled directly or indirectly to the input/output pad.
