Abstract

Patente de Invenção: <B>"FILTRO DIELéTRICO DUPLEXADOR"<D>. Um filtro dielétrico duplexador compreende um bloco dielétrico (110), uma primeira área de filtragem incluindo ressoadores que tem orifícios ressonantes dispostos para passar através de uma primeira e uma segunda superfície (111, 113) do bloco dielétrico (110) de uma maneira substancialmente paralela, uma segunda área de filtragem que inclui ressoadores que têm orifícios ressonantes dispostos para passarem através da primeira e da segunda superfícies (111, 113) do bloco dielétrico (110) de uma maneira paralela; um primeiro padrão condutor (131a-131g) formado nas vizinhanças dos orifícios ressonantes da primeira superfície, para ser, desse modo, conectado ao material condutor coberto com o interior dos orifícios ressonantes e para aplicação de uma capacitância de carregamento aos ressoadores e um acoplamento eletromagnético entre os ressoadores adjacentes, um segundo padrão condutor (140) disposto na primeira superfície da primeira área de filtragem ao longo da direção de arranjo do orifício ressonante e para a formação do acoplamento eletromagnético entre os ressoadores adjacentes, um terceiro padrão condutor (135a-135d) disposto na primeira superfície da primeira área de filtragem para a formação do acoplamento eletromagnético entre os ressoadores adjacentes, e um quarto padrão condutor disposto (141, 145) na primeira superfície para ajuste de freq³ências ressonantes dos ressoadores.
