Abstract:
     The invention is a resonator arrangement structure for reducing passive intermodulation in a diplexer, characterized by that in four annularly distributed, sequentially adjacent resonant cavities in the emission filtering part of the diplexer, the resonant rod in the first resonant cavity is capacitively coupled with that in the second one; and the resonant rod in the first resonant cavity is capacitively coupled with that in the third one or that in the second one is capacitively coupled with that in the fourth one. And the invention realizes a newer better resonator arranging form for a diplexer, simple in structure, convenient to assemble and able to improve and stabilize intermodulation indexes on the original basis, and reducing the intermodulation rework load, able to improve product reliability and reduce production cost.
