ABSTRACT:
A microwave filter includes two resonant cylindrical cavities aligned in parallel along their longitudinal axes, with the cavities offset by one half the cavities' resonant wavelength with respect to one another. Signals to be filtered are coupled into a first, input, cavity through an input coupling and between the input cavity and a second, output, cavity through bridge and mainline couplings formed in a common cavity wall.
