Abstract
A filter for processing an RF signal includes an input port and an output port and a plurality of resonators. The resonators are arranged in a sequentially-coupled arrangement between the input and output ports to affect an RF signal therebetween. Each resonator includes a cavity and resonant element. The resonant elements of at least two resonators are made of two different types of materials to effect higher and lower Q factors for the resonators. The resonators are arranged to provide at least one resonator having a lower Q factor proximate one of the input and output ports while the higher Q factor resonator is provided proximate the inside of the sequentially-coupled arrangement.
