how to design a RF signal generator

Hello, I want to design a RF signal generator. Can you guys kindly let me know how to do so? please help

Sorry if I sound grumpy, but your request is far too broad. Decide what you really want, range, amplitude, impedance, etc. Then use a search engine to find a reference design and take it from there. You may get help with some detail, but you should do the end design and work on it.
