Abstract

UN DISPOSITIVO DE SINTONIZACION DE R.F.COMPRENDE UNA ETAPA MEZCLADORA (M) DE CONMUTACION Y UN OSCILADOR DE SINTONIZACION (O) ACOPLADO A LA MISMA. PARA REDUCIR LA CONTRIBUCION DE RUIDO DE LA ETAPA MEZCLADORA (M), SIN INCREMENTAR LA RADIACION DEL OSCILADOR, SE INCREMENTA LA RELACION DE SEGUIMIENTO DE LA SEN/AL OSCILADORA DE CONMUTACION APLICADA A LA ETAPA MEZCLADORA (M).
