6A
2, improve the superconductor coating film thickness that is used to make the super conductive filter material, improve cross section, thereby improve the power of filter.
When 3, designing superconducting cavity, with thicker line footpath.
Above method is no problem for less (such as several watts) power filter device, but just can not satisfy the demands for the single super conductive filter in the field that power requirement is arranged, in wireless communication base station, transmit signal power from the base station to the mobile phone reaches tens watts, what have surpasses hectowatt, above method just can not meet the demands, because in the microwave communication field, the frequency of process is at the high-frequency current of hundreds of KHZ to several thousand KHZ on the high temperature superconduction wave filter, super conductive filter is for high-frequency current, there is the restriction of a London penetration depth, general this degree of depth approximately is 0.6 micron, simultaneously because the design of superconducting cavity is subjected to the requirement of Design of Filter index, the live width of resonant cavity can not at will increase, and can only improve the current density of superconductor at last.In the prior art, current density that can the actual superconductor that uses is 10
6A has been the limit, and the very fast engineering feasibility that increases considerably current density is little.Therefore, also to be merely able to be several watts and tens watts to the single power of present high temperature superconduction wave filter.Then powerless for tens watts or power up to a hundred.
