| Abstract: | The broadband fast frequency hopping synthesizer, which has the advantages of high stability and fast frequency hopping, is now one of the key technologies of the electronic warfare system. Using the latest technology of direct digital frequency synthesizer with the frequency source can produce reference frequency which is of high speed, high stability, high precision and low noise, and the use of frequency multiplier can increase the frequency and bandwidth. Using DSP as the PN code calculator and control word generator, and FPGA as the control centre, a broadband fast frequency hopping synthesizer can be designed. This paper also presents some key technologies for the design of high-speed PCB. |
