BST铁电移相器材料及其高频介电性能测试研究的中期报告摘要：本报告介绍了一种基于BST(铁电薄膜)的微波移相器件的研究。为了更好地理解BST材料的电学性质，我们测量了不同组成的BST薄膜的介电性能。我们使用复合因子测试方法，测量了BST薄膜的介电响应和损耗，以确定材料的性能。通过测试，我们发现在一定组成范围内，BST薄膜的介电性能优秀，可以满足高频移相器件的要求。此外，我们还研究了BST薄膜的热稳定性和耐久性。结果表明，BST薄膜在高温下具有稳定的性能，并且具有耐久性。通过这些测试，我们对BST材料的性能有了更深入的了解，并为下一步制备高性能的移相器件提供了基础。关键词：BST，移相器件，介电性能，复合因子测试，热稳定性，耐久性Abstract:ThisreportintroducesaresearchonmicrowavephaseshiftersbasedonBST(ferroelectricthinfilm).InordertobetterunderstandtheelectricalpropertiesofBSTmaterials,wemeasuredthedielectricpropertiesofBSTfilmswithdifferentcompositions.WeusedacompositefactortestingmethodtomeasurethedielectricresponseandlossoftheBSTfilmtodeterminetheperformanceofthematerial.Throughtesting,wefoundthatthedielectricpropertiesofBSTfilmsareexcellentwithinacertaincompositionrange,whichcanmeettherequirementsofhigh-frequencyphaseshifters.Inaddition,wealsostudiedthethermalstabilityanddurabilityofBSTfilms.TheresultsshowedthatBSTfilmshavestableperformanceathightemperaturesandhavedurability.Throughthesetests,wehaveadeeperunderstandingoftheperformanceofBSTmaterialsandprovideabasisforthepreparationofhigh-performancephaseshiftersinthefuture.Keywords:BST,phaseshifter,dielectricproperties,compositefactortesting,thermalstability,durability
