Title:ResearchonW-bandorthogonalmixeranditsapplications

BackgroundandSignificance:

Inrecentyears,withtheincreasingdemandforhigh-speedwirelesscommunicationandradarsystems,themillimeter-wavefrequencyband(30GHzto300GHz)hasattractedmoreandmoreattention.W-band(75GHzto110GHz),asapartofthemillimeter-wavefrequencyband,hasmanyuniqueadvantages,suchashighdatarate,widebandwidth,andhighresolution.Therefore,thestudyofW-bandradiofrequency(RF)componentshasbecomeahottopicinthefieldofhigh-frequencyelectronics.

OrthogonalmixersarewidelyusedinRFsystemsforfrequencyconversion.Comparedwithtraditionalmixers,orthogonalmixershavetheadvantagesofhighisolation,lowconversionloss,andbroadbandoperation.However,fewstudieshavebeenconductedonW-bandorthogonalmixers,whichlimitstheiruseinW-bandRFsystems.

ResearchObjectives:

Theobjectivesofthisresearchareasfollows:

1.TodesignandoptimizethestructureofW-bandorthogonalmixerbasedontheSchottkydiode.

2.TosimulateandanalyzevariousperformanceparametersoftheW-bandorthogonalmixer,includingconversionloss,isolation,andbandwidth.

3.TofabricateandtesttheW-bandorthogonalmixerusingmicroelectronicstechnology.

4.ToinvestigatetheapplicationoftheW-bandorthogonalmixerinW-bandradarandcommunicationsystems.

5.ToevaluatetheperformanceoftheW-bandorthogonalmixerandcompareitwithotherexistingmixers.
