| Abstract: | Signal Source is very important in the research,experiment and the development of the hardware circuit system.Combining the research with engineering,the technology of DDS(Digital Direct Synthesis) and PLL(Phase Locked Loop) are combined to design the WCDMA signal.The system may be controlled to set the frequency with the Switch and RS485.The experiment results show that the WCDMA signal soure has good porfornance and actual value in practical application.The signal source has the output frequency range of 1 920~1 980MHz and 2 110~2 170MHz. |
