Abstract

Se proporciona un duplexor que tiene un primer, segundo y tercer puertos y que está adaptado para la conexión entre una antena de enlace ascendente y de enlace descendente, respectivamente, en un sistema de comunicación dúplex por completo. El duplexor tiene primer y segundo transformadores de cuarto de onda conectados entre el primer y el tercer y entre el primer y el segundo puertos, respectivamente. El duplexor tiene un resistor de balanceo conectado entre el tercer puerto y la salida del segundo transformador ubicado en el lado opuesto del primer puerto. El duplexor tiene un circuito de filtro conectado entre la salida del segundo transformador ubicado en el lado opuesto del primer puerto y el segundo puerto.
