Abstract

"FILTRO ANALóGICO DE PASSAGEM DE BANDA". A invenção se relaciona a um filtro analógico de passagem de banda que compreende uma pluralidade de circuitos de escada LC (1), a resposta dos quais é determinada por uma banda de passagem (f~ pi~, f~ ps~) e uma banda de rejeição (dentro dos limites f~ ri~, e f~ rs~) O filtro da presente invenção é caracterizado pelo fato de uma série de circuitos de tanque (5) serem dispostos em paralelo com a carga de filtro, as freq³ências de ressonância dos citados circuitos de tanque coincidem com a freq³ência de corte inferior (f~ pi~) e freq³ência de corte superior (f~ ps~) da banda de passagem do filtro. Adicionalmente, o filtro compreende um resistor de controle (R~ c~) que regula o efeito dos circuitos de tanque no filtro. A citada estrutura pode ser usada para compensar o efeito das limitações reais dos componentes LC (1) para ajustar a resposta do filtro analógico de passagem de banda criado tendo os citados componentes para uma resposta de filtro de passagem de banda ideal.
