Plugging pairing base and pairing method for single-section monolithic crystal filter

The invention relates to a single-section monolithic crystal filter plugging pairing base and a pairing method thereof, and belongs to the technical field of debugging of crystal filters. The base comprises a metal shell cover with eight round holes in the surface, eight round hole contact pins, two radio frequency coaxial connectors, two grounding gaskets, a partition plate, adjustable capacitors with the number matched with that of the metal shell cover, and impedance matching coils with the number matched with that of the metal shell cover. The single-section monolithic crystal filter pairing method comprises the steps of selecting out single-section monolithic crystal filters with similar center frequencies and bandwidths, identifying resonators with smaller resistance in the single-section monolithic crystal filters so as to distinguish the cascade direction, inserting the single-section monolithic crystal filters into a pairing base according to the cascade direction, and matching the single-section mon
