Abstract
A waveguide filter for the transmission of an RF signal comprising a plurality of blocks of dielectric material coupled together in a combined side-by-side and stacked relationship. Each of the blocks defines resonators and includes an exterior surface that is covered with a layer of conductive material and defines internal layers of conductive material with the blocks coupled together. The internal layers of conductive material include regions devoid of conductive material that define internal windows for the transmission of the RF signal between resonators in the side-by-side and stacked blocks. The internal layers of conductive material also include regions devoid of conductive material that define isolated pads of conductive material for the indirect transmission of the RF signal between resonators in the stacked blocks.
