Abstract

UNA ESTRUCTURA DE UN DUPLEXOR PARA EQUIPO RADIO DUPLEX TIENE UN PANEL DE CIRCUITOS DE TRANSMISION CARGADO CON UNA SECCION DE TRANSMISOR Y UN FILTRO DE TRANSMISION PARA FILTRADO DE UNA SEÑAL DE ALTA FRECUENCIA ALIMENTADA DESDE LA SECCION DEL TRANSMISOR. UN PANEL DE CIRCUITO DE RECEPCION INDEPENDIENTE FISICAMENTE DEL PANEL DE CIRCUITOS DE TRANSMISION ESTA CARGADO CON UN FILTRO DE RECEPCION PARA FILTRADO DE UNA SEÑAL DE ALTA FRECUENCIA RECIBIDA Y UNA SECCION DE RECEPTOR PARA RECIBIR LA SEÑAL DE ALTA FRECUENCIA DEL FILTRO DE RECEPCION. UN PANEL DE CIRCUITOS DE CONEXION CONECTA MECANICAMENTE EL PANEL DE CIRCUITOS DE TRANSMISION Y EL PANEL DE CIRCUITOS DE RECEPCION Y SE CARGA CON UN CIRCUITO DE COMPARACION PARA COMPARAR LA FASE DE LA SEÑAL DE ALTA FRECUENCIA QUE SE VA A DAR ENTRADA AL FILTRO DE RECEPCION Y LA FASE DE LA SEÑAL DE ALTA FRECUENCIA A LA QUE DA SALIDA EL FILTRO DE TRANSMISION. CONECTORES ELECTRICOS INTERCONECTAN EL FILTRO DE TRANSMISION Y EL FILTRO DE RECEPCION AL CIRCUITO DE COMPARACION.
