Abstract

<B>COMBINADOR PARA CONEXãO DE UMA PRIMEIRA E DE UMA SEGUNDA ESTAçãO DE BASE A UMA ESTRUTURA DE ANTENA COMPARTILHADA, E MéTODO DE CONEXãO<D> Um sistema e um método efetivamente combinam as comunicações das estações de base de múltiplos sistemas sem fio na mesma estrutura de antena. Em uma implementação, um combinador de sistema sem fio serve como uma interface entre as estações de base do primeiro e do segundo sistemas sem fio ( "primeira estação de base" e "segunda estação de base") e uma antena compartilhada, para, substancialmente, eliminar um ruído espúrio da primeira estação de base nas freq³ências alocadas para a segunda estação de base e impedir a potência de transmissão da primeira estação de base de alimentar o circuito de recepção da segunda estação de base em uma configuração de antena compartilhada. O combinador inclui um primeiro filtro combinador, entre um duplexador da primeira estação de base e um ponto de conexão comum, e um segundo filtro combinador, entre um duplexador da segunda estação de base e o ponto de conexão comum. O primeiro filtro combinador filtra um ruído espúrio gerado pelo transmissor de primeira estação de base nas freq³ências fora da banda de freq³ência alocada para a primeira estação de base, por exemplo, usando um filtro de passagem de banda ou de rejeição de banda de valor Q alto. O segundo combinador filtra a potência de sinal em freq³ências fora da banda de recepção da segunda estação de base, para impedir uma potência de sinal de transmissão da primeira estação de base de alimentar o circuito de recepção da segunda estação de base, desse modo impedindo uma intermodulação.
