  • Combline filter and method of use thereof
    Patent number: 6359533
    Abstract: A radio frequency mechanical filter (10) of the resonant type employs a plurality of parallel spaced-apart resonators (40) disposed within a housing (16) defining a cavity. The resonators are supported at their first ends (46) to one wall (20) of the housing (16), with the remaining ends of the resonators being unsupported. A TEFLON support bracket (12) is disposed across the resonators (40) at points between the ends (44, 46) of the resonators. In one form, the support bracket (12) is movable along the length of the resonators to change the center frequency and bandwidth response of the filter.
