Abstract

Transceptor de multiplexión de frecuencia con las siguientes características: un bloque de banda de base (18), una trayectoria de emisión (S1) con un oscilador local (6) y una primera trayectoria de recepción (E1) están conectados entre sí de tal manera que se emite y se recibe al mismo tiempo sobre frecuencias diferentes entre sí, una trayectoria de emisión auxiliar (S2) con una mezcladora (11) alimentada por el oscilador local (6) está conectada con la primera trayectoria de recepción (E1) y añade a la señal de recepción (E1) una señal, cuya fase está desplazada 180° con respecto a la fase de la porción de diafonía en la primera trayectoria de recepción (E1) en el punto de superposición respectivo de la suma y que presenta la misma frecuencia o bien la misma gama de frecuencias que la señal de emisión, la trayectoria de emisión auxiliar (S2) se puede activar, independientemente de la primera trayectoria de emisión (S1) por el bloque de banda de base (18) de tal manera que en la salida dela mezcladora (11) se encuentra la señal de compensación.
