Signal generator is a kind of electronic devices that generate repeating or nonrepeating electronic signals which are generally used in designing, testing and so on. Under a certain reference frequency, it is able to control the output main signal frequency by selecting the suitable mixed signal at the output with bandwidth filter. This paper introduces a design and implementation of a high-frequency signal generator based on the DDS mixing principle. The generator uses the characteristics of D/A convertor as DDS output frequency spectrum. Experiments show that using the bandwidth filter, most of the spurious signals are removed and the main frequency is confined, thus, signal of 101MHz could be achieved significantly. Additionally, it is observed that the Sine wave is finally obtained from the figure and the filter circuit is able to confine the signal bigger than 30dB for the frequency over 101MHz.
