Abstract

LA FRECUENCIA DE UN OSCILADOR DE CRISTAL DE VOLTAJE DE UN CONTROLADO PUEDE SER INFLUENCIADO DE UNA MANERA CONVENCIONAL MEDIANTE ELEMENTOS DE DIODO VARICAP FORMANDO LA CAPACIDAD DE CARGA DEL OSCILADOR DE CRISTAL. EN ORDEN A OBTENER UNA AMPLIA GAMA DE ARRASTRE DE FRECUENCIA, LA CAPACIDAD DE CARGA ES ALTERNATIVAMENTE INTERRUMPIDA DE FORMA CONOCIDA. DE ACUERDO CON LA INVENCION UN DIODO LLAVE DE CAMBIO DE BANDA 846) PUEDE SER EMPLEADO COMO CONMUTADOR SI EL TIEMPO DE CARGA DEL DIODO DE ESTE DIODO ES TANTO O MAS LARGO QUE EL CICLO DEL OSCILADOR. MEDIANTE ELEMENTOS DE CONTROL DE VOLTAJE DE BAJA FRECUENCIA EL DIODO SE AUTOCONMUTA DENTRO DEL CICLO DEL OSCILADOR, DE MODO QUE SE HAGA POSIBLE LA REGULACION PROPORCIONAL DE LA FRECUENCIA.
