Dielectric filter |
摘要 |
<p>A dielectric filter is adapted to show a specified coupling capacitance without inadvertently affecting the resonance frequency, in which a dielectric ceramic block is provided with two or more than two resonant conductors arranged in parallel, a conductive circuit film is formed on the open-circuit end surface of said dielectric ceramic block and electrically separated from the inner conductive films of the resonant conductors by arranging insulation gaps therebetween to capacitively couple the conductive circuit film and the resonant conductors by way of the insulation gap. <IMAGE></p> |
