Abstract

Nei filtri monolitici di materiale ceramico che richiedono stadi di risuonatori formati in un blocco di materiale dielettrico che debbono essere elettricamente accoppiati insieme attraverso componenti discreti, precisamente fili (44 e 46), un sostanziale risparmio di spazio come anche perfezionate prestazioni elettriche e meccaniche possono essere realizzate mediante il montaggio dei fili (44 e 46) in cavità di disaccoppiamento (36 e 40) quando tali cavità di disaccoppiamento sono disponibili ed appropriatamente posizionate rispetto ad altri elementi di risuonatori nel filtro.
