Abstract
Perfeccionamientos en sistemas duplex de radiotransmisión por microondas, para la transmisión de datos analógicos y digitales entre estaciones emisoras-receptoras que se mueven a lo largo de recorridos predeterminados, y estaciones emisoras-receptoras dispuestas a separaciones predeterminadas en éste recorrido y eficaces en ambos sentidos del recorrido, en el que las estaciones de un recorrido están enlazadas con una estación emisora-receptora central, caracterizados porque las estaciones móviles y/o fijas presentan una derivación de emisión con una entrada de modulación y un oscilador de microondas común para la derivación de emisión y recepción, y una derivación de recepción con un mezclador de microondas, un demodulador y una salida de modulación, porque las derivaciones de emisión y recepción están conectadas a un circulador a cuyo tercer brazo que se halla entre el brazo enlazado con la derivación de emisión y el enlazado con la derivación de recepción, está conectado un acoplador, alque están conectadas dos antenas con direcciones de radiación desplazadas 180º, porque en la derivación de emisión está previsto un circuito de estabilización para el oscilador de microondas y porque una señal del oscilador de microondas disminuida en la amortiguación de desacoplamiento del circulador, se alimenta a través de la derivación desacoplada del circulador al mezclador de microondas en la derivación de recepción, y con la señal de recepción se transforma a la frecuencia intermedia que se alimenta a un siguiente amplificador y demodulador cuyas señales de salida se llevan a la estación principal a través de un cable de señales.
