Abstract

La invención se refiere a un dispositivo de transmisión o de transmisión/recepción que tiene una estructura de ruta de transmisión que hace posible incrementar el intervalo de variación de la potencia de transmisión sin degradar la relación señal a ruido. La atenuación se logra en parte en una unidad interna 5 y en parte en una unidad externa 4 con la ayuda de un circuito de conmutación 25 que pone en corto circuito o de otro modo el amplificador 20 de la antena 21.
