Abstract
Un sintetizador de frecuencia (200) que utiliza un sintetizador digital directo (DDS) (204) para generar una señal periodica muy precisa. La señal de salida del DDS (204) se filtra en un filtro de paso de banda que utiliza un bucle o circuito de enganche de fase (PLL) de limpieza o depuracion (214) para producir una señal de referencia espectralmente pura y promover un rápido tiempo de estabilizacion total. Un segundo bucle de enganche de fase o bucle de enganche de fase primario (220), que tiene un tiempo de estabilizacion mucho más rápido que el primer PLL (214), ajusta la frecuencia de la señal de referencia generada por el PLL de limpieza o depuracion (214). En una modalidad, el sintetizador de frecuencia DDS (204) tiene un convertidor digital a analogico (DAC) (206) acoplado al PLL de limpieza o depuracion (214). Otra modalidad (300) alimenta el bit más significativo (MSB) (310) o el bit de exceso o excedente del acumulador DAC (306) hacia el PLL de "limpieza o depuracion" (318). Otra modalidad (400) utiliza un aparato de conmutacion para derivar al PLL "limpieza o depuracion" (410) mientras se está estabilizando en una nueva frecuencia.
