Abstract
본 발명은 주파수신호 합성기에 관한 것으로, 기준주파수 신호를 발생하는 기준주파수 발진기와 ; 상기 기준주파수 신호를 소정수로 체배하여 출력하는 제 1 주파수 체배수단과 ; 발생시키고자 하는 주파수에 따라 달라지는 차분위상값을 출력하는 제어부와 ; 상기 차분위상값을 축적한 후 그에 대응되는 정현파진폭값을 아날로그값으로 변환하여 출력하며 상기 기준주파수 신호를 동작클럭으로 하는 직접 디지탈 주파수합성수단과 ; 상기 직접 디지탈 주파수합성수단의 출력을 소정수로 체배하여 출력하는 제 2 주파수 체배수단과 ; 상기 제 1 주파수 체배수단 및 제 2 주파수 체배수단의 출력을 혼합하여 출력하는 혼합기 ; 및 상기 혼합기의 출력중 소정 주파수대역의 신호만을 필터링하여 출력하는 필터수단을 구비하여 상기 제어부의 차분위상값을 고속으로 변화하도록 함으로써 출력되는 주파수가 고속으로 스위칭되는 것을 특징으로 한다.The present invention relates to a frequency signal synthesizer, comprising: a reference frequency oscillator for generating a reference frequency signal; First frequency multiplication means for multiplying and outputting the reference frequency signal by a predetermined number; A control unit for outputting a differential phase value that varies depending on the frequency to be generated; Direct digital frequency synthesizing means for accumulating the difference phase value and converting the corresponding sinusoidal amplitude value into an analog value and outputting the analog signal; Second frequency multiplication means for multiplying and outputting the output of said direct digital frequency synthesizing means by a predetermined number; A mixer for mixing and outputting the outputs of the first frequency multiplication means and the second frequency multiplication means; And a filter means for filtering and outputting only signals of a predetermined frequency band among the outputs of the mixer to change the difference phase value of the controller at high speed so that the output frequency is switched at high speed.
