As　a　key　step　to　guarantee　passive　intermodulation　(PIM)　test　accuracy,　PIM　calibration　for　PIM　tester　draws　great　attention　these　days.　This　paper　provides　three　solutions　to　realize　tunable　PIM　calibration　standard　sources　for　PIM　tester　calibration.　Two　types　of　nonlinearity　sources　are　applied　while　three　circuit　or　cavity　structures　are　developed　to　control　these　sources.　By　using　different　strategies,　the　proposed　PIM　sources　can　generate　controllable　PIM　references　with　different　ranges　that　cover　most　PIM　test　ranges.　In　the　experiments,　the　PIM　signal　stability　is　evaluated　as　well　as　PIM　dynamic　range.　They　show　the　minimal　PIM　fluctuation　as　less　as　1dB,　while　the　maximal　dynamic　range　can　reach　50dB.　As　these　solutions　have　various　sizes　and　function,　they　can　be　utilized　according　to　different　test　requirements　and　easily　integrated　with　PIM　tester.　These　solutions　can　help　develop　new　generation　of　PIM　testers.
