Abstract

Repetidor bidireccional de impedancia negativa y con impedancias terminales de valores diferentes conectadas a sus extremos respectivos, caracterizado porque la impedancia aparente del repetidor, se elige con relación a las impedancias terminales y a la constante de propagación del repetidor, de tal modo que se obtenga una paridad de impedancia entre el repetidor y una de las impedancias terminales, dentro de una amplia banda de frecuencias.
