Linear spinning disk atomiser of ultra wide band predistortion

The utility model provides a linear spinning disk atomiser of ultra wide band predistortion, include: a branch line coupler for behind first input end incoming signal, from the direct output signal of first direct end, and export and the reverse signal of first direct end constant amplitude from first coupling end, move the looks ware, its input is connected to a branch line coupler's first direct end, a nonlinear generator for produce the curve of gain expansion and phase place expansion or compression, and output first via signal, the 2nd nonlinear generator for produce the curve of gain expansion and phase place expansion or compression, output second way signal, and fourth branch line coupler for synthesize first via signal and second way signal, and the signal of output after synthetic. Be used for power amplifier with this linear spinning disk atomiser of ultra wide band predistortion, the for example linearisation of travelling wave tube has greatly promoted the linearity, has important engineering app
