| Abstract: | Direct Digital Synthesizer is characterized by high frequency resolution, low phase noise and excellent frequency spectrum, which can be applied to the design of practicality circuit with the Multiplier. The design gets rid of the default, which causes the circuit to work at low frequency, with only DDS technology. The design can get the circuit to work at high frequency, and get high frequency resolution and excellent frequency spectrum. Chip AD9854 is applied to the design named frequency hopping synthesizer at L wave band. The circuit has the simple structure and the reasonable solidity. The circuit can work stably and reliably, and it can be used and maintained conveniently. |
