Abstract

"FILTRO RESSONADOR". A invenção refere-se a um filtro ressonador sintonizável. Em cada cavidade de ressonador do filtro, há um elemento dielétrico de sintonização móvel (728; 748) para ajustar a freq³ência natural do ressonador. Os elementos de sintonização são vantajosamente arranjados de modo a serem movimentados por um controle comum implementado por uma barra (708) que os une para alterar a banda do filtro através de deslocamentos iguais das freq³ências naturais dos ressonadores. Quando o elemento de sintonização é movimentado horizontalmente em direção às laterais a partir do eixo do ressonador (710; 720; 730; 740; 750; 760), o comprimento elétrico e a freq³ência natural do ressonador são alterados. Nesse caso, quando sub-bandas são utilizadas, não é necessário sintonizar os filtros separadamente para cada sub-banda no estágio de fabricação, uma vez que a sub-banda pode ser escolhida quando o filtro é colocado em uso. Os elementos de sintonização também podem ser móveis em cada ressonador separadamente para implementar a sintonização básica em relação à fabricação do filtro. A sintonização básica pode ser automatizada; em outras palavras, pode ser realizada sem a necessidade de trabalho manual inconveniente.
