发明名称 Dielectric filter
摘要 <p>In a dielectric filter comprising a dielectric block provided with a plurality of through holes bored from the top all the way to the bottom thereof and arranged in parallel with each other, the peripheral walls of the through holes being coated with an inner conductor to produce so many dielectric coaxial resonators, a non-short-circuiting section is formed on the top of the dielectric block, by cutting out at least one of the edges of the top running in parallel with the direction of linking the resonators. With this arrangement, an interstage coupling section can be formed accurately and easily regardless in the dielectric filter if a number of dielectric filters being manufactured on a mass production basis show positional displacements and/or dimensional deviations from the specified values in the manufacturing process. &lt;IMAGE&gt;</p>
