Abstract:
1. A system comprising: a dielectric filter including a single dielectric slab shaped to define a plurality of dielectric resonators separated and coupled by irises defined by slots formed in the dielectric slab, including a first end iris and a second end iris, the irises are electrically conductive coated except an end wall face of the first end iris and an end wall face of the second end iris and each resonator having a top wall, side walls and a bottom wall; and a hollow waveguide having a groove configured to receive the dielectric filter and provide metal on or proximate to the top wall, the side walls and the bottom wall of the plurality of dielectric resonators, the hollow waveguide configured to provide access to the groove to interchange the dielectric filter; wherein a width of the plurality of resonators fits a width of the groove within the hollow waveguide to allow insertion and removal of the dielectric filter into and out of the hollow waveguide where the top, side and bottom walls of the resonators are in contact with inner sides of the groove of the hollow waveguide.
