Low-pass filter

摘要

A low-pass filter is obtained by inserting a third dielectric substrate having a shielding electrode on its upper surface between a first dielectric substrate having microstriplines on its upper surface and a second dielectric substrate having capacitor electrodes on its upper surface, stacking fourth and fifth dielectric substrates having ground electrodes on upper surfaces thereof on both sides of the first to third dielectric substrates, and stacking a dielectric sheet on the uppermost portion.
