Abstract
A waveguide filter comprising a base block of dielectric material defining at least first and second resonators and a bridge block seated on top of the base block and defining at least a third resonator. In one embodiment, the base block comprises first and second base blocks that have been coupled together in an end to end relationship. An external transmission line or an interior RF signal transmission window or an RF signal transmission bridge provides a cross-coupling RF signal transmission path between the first and second resonators. At least first and second interior RF signal transmission windows provide a direct RF signal transmission path between the first and third resonators and the second and third resonators respectively.
