Multilayer band pass filter with a zero point forming capacitor |
摘要 |
A multilayer band pass filter includes a zero point forming capacitor formed by a plurality of capacitors connected in series between first and second extension electrodes, and intermediate capacitors connected between each pair of adjacent series capacitors and the open end of a core conductor. Therefore, zero points can be formed at the lower and upper limits of a given band. The capacity of these capacitors is adjustable via extension electrodes which extend outside the baked ceramic casing, thereby allowing adjustment to be made to the zero point.
