Abstract
Various embodiments of an integrated multiband bandpass apparatus based on concentric dielectric ring resonators includes one or more radio frequency (RF) input transmission lines for receiving multi-band RF signals, multiple RF output transmission lines for receiving and transmitting multiple single-band RF signals, and a set of dielectric ring resonators coupled in between. The disclosed integrated multi-band bandpass apparatus based on dielectric ring resonators can support at least two operation modes, i.e., a multi-band bandpass filtering mode when used in one direction and a multi-band bandpass multiplexing mode when used in an opposite direction. When operating in the multi-band bandpass filtering mode, the multiple dielectric ring resonators can be used to simultaneously filter multi-band RF signals into multiple single-band bandpass signals. When operating in the multi-band bandpass multiplexing mode, the dielectric ring resonators can be used to multiplex multiple single-band bandpass signals into a multi-band RF signal.
