摘要：A waveguide filter comprising a base block of dielectric material defining atleast first and second resonators and a bridge block seated on top of the base block anddefining 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 signaltransmission bridge provides a cross-coupling RF signal transmission path between thefirst and second resonators. At least first and second interior RF signal transmissionwindows provide a direct RF signal transmission path between the first and thirdresonators and the second and third resonators respectively.
