るヘリカルフイルタ。 It consists of a plurality of bobbins around which helical coils are wound, a case on the outside of the bobbins, and a dielectric material that moves up and down over the upper part of each bobbin to change the distributed capacitance between the helical coil and the case. A helical filter characterized in that the outer diameter of the upper part of the bobbin that moves up and down is smaller than that of the lower part.
