Abstract

Un circuito de sintonizacion de antena de un sintonizador con un dispositivo de conmutacion de banda, que puede eliminar una perturbacion de imagen y una perturbacion debido a una frecuencia de banda de UHF a la recepcion de una banda alta y además eliminar una perturbacion a una frecuencia más alta que la frecuencia de imagen a la recepcion de una banda baja; a la recepcion de una banda alta, se provee una bobina para conectarse entre una terminal de entrada y una primera bobina de banda alta, y un primer circuito trampa incluyendo un primer capacitor y la bobina 32 se establece entre la terminal de entrada y una terminal de salida, y además se forma un segundo circuito trampa incluyendo un segundo capacitor y una segunda bobina de banda alta.
