Abstract

See full text

A dual-band filtering switch based on a single quad-mode dielectric resonator (DR) includes: a first printed circuit board (PCB) provided thereon with an input terminal; a second PCB provided thereon with an output terminal; a shielding shell arranged between the first and second PCBs and enclosing a shielding cavity together with the first and second PCBs; and a single quad-mode DR arranged in the shielding cavity. The first and second PCBs each include a feeding layer, a dielectric layer, and a ground layer that are stacked in sequence. The feeding layers of the first and second PCBs each include a microstrip line and a switching circuitry connected to the microstrip line, and the feeding layer is in contact with a surface of the DR to realize a switching function of the filtering switch. The proposed filtering switch feature low loss transmission and high selectivity with dual-band operation, miniaturization with the fewest resonators and friendly-integration, simultaneously.
