METHOD FOR MANUFACTURING RESONANT POLES, RESONANT POLES AND CAVITY FILTERS

摘要

Embodiments in the invention disclose a method for manufacturing resonant poles, which comprises the following steps: homogeneously mechanical mixing 88wt%-98wt% Fe-Ni alloying powder, 1wt%-8wt% carbonyl iron powder and 1wt%-8wt% carbonyl nickel powder mechanically; shaping the mixture powders after being homogeneously mixed into green body of the resonant poles; and continuously sintering and heating by annealing the green body of the resonant poles. Also, embodiments in the invention provide a kind of resonant poles and cavity filters. The advantages of using the method for manufacturing resonant poles of the embodiments in the invention is: the production efficiency being greatly improved, the raw material loss being cut down in a large degree, and the alloying gradients agglomeration of the resonant poles of the embodiments in the invention being reduced to a minimum, big and uneven defects of the microstructures being eliminated, hence the performance index and stability of the corresponding products being increased.
