Abstract

SINTETIZADOR DE FRECUENCIAS. BASADO EN UNA ESTRUCTURA DE BUCLE DE ENGANCHE EN FASE, COMPUESTO POR UN GENERADOR DE SEÑAL DE REFERENCIA (1), UN PRIMER DETECTOR DE FASE (2), UN FILTRO PASO BAJO (3), UN VCO (4) Y UN DIVISOR DE FRECUENCIA (5). PARA CONSEGUIR UNA CONMUTACION DE CANAL MAS RAPIDA, PERO MANTENIENDO EL DISEÑO DE LOS FILTROS LO MAS SENCILLO POSIBLE, SE INCLUYE UN SEGUNDO DETECTOR DE FASE (6) QUE RECIBE LA SEÑAL DE REFERENCIA (9) Y UNA SEGUNDA SEÑAL DE SALIDA (11) PROCEDENTE DEL DIVISOR DE FRECUENCIA (5) Y DESFASADO 90G CON RESPECTO A SU OTRA SEÑAL DE SALIDA (10), Y QUE GENERA UNA SEGUNDA SEÑAL DE ERROR DE FASE (13), EN CUADRATURA CON LA PRIMERA SEÑAL DE ERROR DE FASE (12), QUE ES FILTRADA POR UN SEGUNDO FILTRO PASO BAJO (7) DANDO LUGAR A UNA SEGUNDA SEÑAL DE ERROR DE FASE FILTRADA (15). LAS DOS SEÑALES DE ERROR DE FASE FILTRADA (14, 15) SE LLEVAN A UN CORRELADOR CUADRATICO (8) CUYA SALIDA ALIMENTA AL VCO (4), Y ES DE AMPLITUD PROPORCIONAL A LA DIFERENCIA DE FRECUENCIAS ENTRE LA SEÑALDE REFERENCIA (9) Y CUALQUIERA DE LAS SEÑALES DE SALIDA (10, 11) DEL DIVISOR DE FRECUENCIA (5).
