Abstract

Un resonador dieléctrico diseñado de tal forma que substancialmente no hay ninguna pérdida en un conductor sobre la superficie de un estuche que forma una cavidad protegida, y de tal manera que la Q no cargada y la frecuencia resonante cambiarse independientemente una de otra. Un bloque dieléctrico cilíndrico que tiene un par de electrodos formados sobre sus dos superficies opuestas, está dispuesto en un estuche metálico de cavidad protegida, de tal modo que uno de loe electrodos está en contacto con una superficie del fondo interior del estuche de cavidad protegida. Este electrodo está conectado eléctricamente al estuche de cavidad protegida mediante soldadura o algo similar.
