Benefiting　from　the　advantages　of　photonic　technologies,　the　microwave　photonic　phase　shifter　(MPPS)　has　become　a　key　technical　enabler　for　broadband　and　high-frequency　signal　processing.　However,　in　all　previously　reported　MPPS　schemes,　the　spurious　free　dynamic　ranges　(SFDR)　of　the　systems　are　all　limited,　which　results　from　the　inherent　nonlinear　of　the　electro-optic　modulator.　Here,　our　objective　is　to　propose　a　novel　MPPS　structure,　where　the　nonlinear　distortions　can　be　effectively　suppressed　via　multi-order　optical　sidebands　vector　manipulation　(MOSVM).　In　parallel,　the　power　efficiency　of　the　system　can　also　obtain　obvious　improvement　at　the　same　received　optical　power　of　the　photodetector　(PD),　thus　achieving　an　MPPS　with　a　significantly　enhanced　SFDR.　Besides,　this　structure　can　be　easily　expanded　to　form　a　multichannel　MPPS　by　the　means　of　wavelength-division　multiplexing　techniques.　In　the　experiments,　we　investigated　the　proposed　MPPS　by　utilizing　the　two-tone　signal　test,　the　sweep　frequency　signal　test,　the　wideband　signal　transmission　test,　and　the　scalability　capability　test.　The　measured　results　indicate　that　the　SFDR　of　the　proposed　MPPS　system　can　obtain　over　20-dB　improvement,　and　the　wideband　signal　transmission　and　the　OAM　beam　based　on　the　MPPS　achieve　better　performances.　As　such,　a　large-SFDR　MPPS　is　first　proposed　and　experimentally　demonstrated　in　this　paper.　IEEE
