Abstract

Perfeccionamientos en amplificadores de microondascaracterizados porque cada amplificador comprende: un circulador de microondas de entrada que tiene un primersegundo y tercer accesos: un dispositivo de acoplamiento de microondas de salida que tiene por lo menos un primersegundo y tercer accesos: medios para acoplar una señal de entrada al primer acceso del circulador de entrada; medios para derivar una señal de salida del segundo acceso del dispositivo de salida; medios para acoplar una etapa amplificadora entre el segundo acceso del circulador de entrada y el primer acceso del dispositivo de salida; y un dispositivo de derivación de señal acoplado entre los terceros de salidapar a reducir la pérdida de transmisión del amplificador en condiciones de falta de energía o de fallo de la etapa amplificadora.
