Abstract

La presente invención se refiere a un dispositivo para rechazo de señales radioeléctricas interferentes que comprende un diplexor de entrada, un diplexor de salida, dos conversores de frecuencia y un filtro SAW caracterizado donde mediante un proceso de separación, primera conversión, filtrado, segunda conversión y mezcla se eliminan de una señal de entrada compuesta de canales de televisión un conjunto de señales radioeléctricas interferentes las cuales están situadas en frecuencia por encima de un canal de televisión predeterminado que se selecciona mediante un conmutador que puede ser actuado de forma remota y que está alimentado mediante una fuente de alimentación interna o externa realizándose esta última a través del conector de salida.The present invention relates to a device for rejection of interfering radio signals comprising an input diplexer, an output diplexer, two frequency converters and a SAW filter characterized by a separation process, first conversion, filtering, second conversion and mixing a set of interfering radio signals which are in frequency above a predetermined television channel that is selected by a switch that can be operated remotely and that is powered is removed from an input signal composed of television channels by means of an internal or external power supply, the latter being carried out through the output connector.
