Low-pass filter.

摘要

A low-pass filter is obtained by inserting a third dielectric substrate (32) having a shielding electrode (31) on its upper surface between a first dielectric substrate (3) having microstriplines (1, 2) on its upper surface and a second dielectric substrate (7) having capacitor electrodes (4 to 6) on its upper surface, stacking fourth and fifth dielectric substrates (11, 10) having ground electrodes (8, 9) on upper surfaces thereof on both sides of the first to third dielectric substrates, and stacking a dielectric sheet (12) on the uppermost portion. <IMAGE>
