  • Patent number: 7973621
    Abstract: A HOM attenuated high frequency resonator provided with a cylindrical resonator cavity on the outer surface of which are arranged three circular tapered waveguides with two symmetrically arranged ridges each, the cut-off frequency of the waveguide base mode being kept constant over the length of the waveguides by varying the height of the ridges, and the ridge waveguides being provided at their end of the smaller diameter with an impedance transformer each for the broadband adjustment of the coaxial line is to be cost-efficiently manufacturable as a compact structure and is to be of improved attenuation properties while at the same time having, relative to prior art arrangements, a high shunt impedance for the fundamental modes.
