Abstract

FILTRO RESSONADOR AJUSTÁVEL Filtro ressonador ajustável (200), cuja banda de operação pode ser mudada por meio de um ajuste único. A freqüência natural de cada ressonador (210, 220) é afetada, além da disposição básica de sintonia, por um circuito de ajuste (ACI), que inclui um elemento de sintonia fixa (280) na cavidade do ressonador e uma peça de ajuste (290) fora da cavidade. O elemento de sintonia tem um acoplamento eletromagnético a uma estrutura básica do ressonador. O circuito de ajuste é funcionalmente uma curta linha de transmissão, que é "vista" pelo ressonador como uma reatância de determinado valor. Pela alteração do comprimento elétrico da linha de transmissão, são alterados o valor da reatância, o comprimento elétrico e a freqüência natural de todo o ressonador. A mudança é implementada na peça de ajuste por meio de comutadores ou por uma peça dielétrica móvel. No filtro do ressonador, cada ressonador tem um circuito de ajuste similar e os circuitos de ajuste têm um controle comum (CNT) para a mudança da banda do filtro. Quando a divisão de sub-banda estiver em uso, os filtros não precisam ser ajustados separadamente para cada sub- banda em conexão com a fabricação. Não são necessárias peças móveis dentro da carcaça do filtro. Fig. 2a.
