Manufacturing method of high flatness index broadband high-power attenuator

The invention provides a manufacturing method of a high flatness index broadband high-power attenuator. The manufacturing method of the high flatness index broadband high-power attenuator is used for solving the problems that in the prior art, flatness compensation of a broadband high-power attenuator needs additional processing steps, is low in efficiency and high in cost. According to the manufacturing method of the high flatness index broadband high-power attenuator, a capacitance effect of the high flatness index broadband high-power attenuator is used for improving a flatness index, not only is design simple, but also a production process can be simplified, production cost is reduced, and production efficiency is improved.
