Abstract

Provê-se um filtro de bloco de cerâmica com uma série de orifícios de transmissão espaçados entre si, e um orifício de retenção; onde o filtro possui uma proporção entre diâmetro de orifício de filtro e altura de filtro de 0,16-0,2 : 1, e uma proporção entre diâmetro orifício de transmissão e distância entre orifícios de transmissão de 0,45-0,5 : 1. O orifício de retenção fica espaçado por uma distância de 1,5-2 vezes a distância entre os referidos pelo menos dois orifícios de transmissão. O ponto zero do filtro é controlado sem afetar parâmetros cruciais, tais como dimensões do filtro, perda por inserção e atenuação, apenas ajustando-se a proporção entre o diâmetro do orifício de transmissão e a altura do filtro, e a proporção entre o diâmetro do orifício de transmissão e a distância entre os orifícios de transmissão.A ceramic block filter is provided with a series of spaced transmission holes, and a holding hole; where the filter has a ratio of filter hole diameter to filter height of 0.16-0.2: 1, and a ratio between transmission hole diameter and transmission hole distance of 0.45-0.5: 1. The retaining hole is spaced 1.5-2 times the distance between said at least two transmission holes. The zero point of the filter is controlled without affecting crucial parameters, such as filter dimensions, insertion loss and attenuation, just by adjusting the ratio between the diameter of the transmission hole and the height of the filter, and the ratio between the diameter of the filter. transmission hole and the distance between the transmission holes.
