| Abstract: | In millimeter wave synthesized frequency-sweeping signal generators,the major properties in sweeping states,such as sweeping accuracy,sweeping time etc.,play a key role in measurement precision and efficiency.Sweeping nonlinearity compensation is of critical importance in the realization of high sweeping accu- racy and fast sweeping speed.An analysis is made of the mechanism for sweeping nonlinearity occurrence,fol- lowed by an introduction of the key technologies of nonlinearity compensation in the millimeter-wave frequency synthesizer.The compensation circuits are designed and put into practical use with remarkable performance im- provement. |
