Abstract

"FILTRO ELéTRICO PARA FILTRAR BAIXAS FREQUêNCIAS PARA PROTEçãO DE UM CIRCUITO ELéTRICO CONTRA PULSOS DE ALTA TENSãO, UNIDADE DE COMUNICAçãO, E, FILTRO DE PASSA-ALTO". A invenção refere-se a um filtro elétrico para filtrar baixas freq³ências de maneira a proteger um circuito elétrico contra ESD. Um filtro de passa-alto (1) para filtrar as baixas freq³ências é usado no trajeto de sinal entre o conector de antena (2) e um circuito elétrico (3) em uma unidade de comunicação. Através do conector de antena diferentes antenas podem ser conectadas. O filtro de passa-alto (1) para filtrar baixas freq³ências é erigido com uma capacitância (C1) no trajeto serial e uma indutância (L1) no trajeto paralelo. O filtro de passa-alto (1) permite a proteção do circuito elétrico subseq³ente (3). Sob ainda outro aspecto o filtro de passa-alto tem uma freq³ência de corte inferior à freq³ência de corte mais baixa de um separador de radio freq³ência no circuito elétrico.
