description | A ceramic dielectric block filter is manufactured by forming a block of uncured dielectric material that includes a plurality of holes formed there through which extend through the dielectric block to intersect top and bottom surfaces of the dielectric block (10), curing the dielectric block by sintering it (10), coating exterior surfaces of the cured dielectric block and surfaces within the holes by at least partially immersing the dielectric block into a viscous, thixotropic electrically conductive liquid (20), heating the dielectric block to dry the electrically conductive liquid (40), and at least locally removing from the top surface of the dielectric block electrically conductive material surrounding at least one hole (50).
On fabrique un filtre bloc diélectrique en céramique en formant un bloc d'un matériau diélectrique non durci qui comprend une multiplicité de trous s'étendant à travers le bloc diélectrique de façon à entrecouper les surfaces supérieure et inférieure du bloc diélectrique (10), en faisant durcir le bloc (10) par frittage, en appliquant un revêtement sur les surfaces externes du bloc diélectrique durci et sur les surfaces internes des trous par l'immersion d'au moins une partie du bloc diélectrique dans un liquide électroconducteur visqueux et thixotrope (20), en chauffant le bloc afin de faire sécher le liquide électroconducteur (40) et en enlevant au moins localement, de la surface supérieure du bloc, du matériau conducteur entourant au moins un trou (50). |
