【摘要】：近年來(lái),射頻微波技術(shù)極大地促進(jìn)了各行各業(yè)的發(fā)展,小型化、低功耗、低成本、高集成度成為微波電路與系統(tǒng)的主要發(fā)展趨勢(shì)。介質(zhì)集成懸置線是一種性能非常優(yōu)良的新型微波傳輸線系統(tǒng),其具有低損耗、低色散、低成本、自封裝等特性。但是介質(zhì)集成懸置線電路自封裝于多層電路板內(nèi)部,難以直接進(jìn)行測(cè)試,此外,為了將具有不同優(yōu)點(diǎn)的傳輸線集成在同一電路中,構(gòu)建高度集成化的射頻前端電路系統(tǒng),因此,高性能的介質(zhì)集成懸置線到微帶/CPW等平面?zhèn)鬏斁�的微波過(guò)渡電路是研究的關(guān)鍵技術(shù)之一。介質(zhì)集成懸置線電路是一個(gè)全新的設(shè)計(jì)平臺(tái),但是在現(xiàn)有的EDA電路仿真軟件中,沒(méi)有相關(guān)的電路模型,介質(zhì)集成懸置線電路的設(shè)計(jì)仍然需要進(jìn)行大量的EM仿真。所以,構(gòu)建精準(zhǔn)的介質(zhì)集成懸置線基本無(wú)源器件模型,不僅能夠更加方便、高效地進(jìn)行介質(zhì)集成懸置線電路的設(shè)計(jì),同時(shí)開(kāi)可以極大地促進(jìn)介質(zhì)集成懸置線平臺(tái)的發(fā)展與應(yīng)用。介質(zhì)集成懸置線電感所以作為介質(zhì)集成懸置線平臺(tái)最重要的無(wú)源器件之一,其建模是亟待解決的關(guān)鍵問(wèn)題之一。本課題針對(duì)不同的空氣腔高度和介質(zhì)基板材料,設(shè)計(jì)了新型的介質(zhì)集成懸置線到微帶/CBCPW的過(guò)渡結(jié)構(gòu)。新型的介質(zhì)集成懸置線微波過(guò)渡電路能夠滿足dc-25 GHz范圍內(nèi),介質(zhì)集成懸置線電路的測(cè)試需要,這為介質(zhì)集成懸置線電路的發(fā)展和應(yīng)用奠定了堅(jiān)實(shí)的基礎(chǔ)和良好的保障。本課題提出了新型的介質(zhì)集成懸置線螺旋電感,以及介質(zhì)挖除的雙邊走線介質(zhì)集成懸置線螺旋電感;這兩種新型的電感能夠大幅度地提高電感的Q值。本課題對(duì)基于介質(zhì)集成懸置線平臺(tái)的介質(zhì)集成懸置線螺旋電感進(jìn)行了系統(tǒng)化的建模,并介紹了它的open-short參數(shù)提取方法以及物理基等效電路模型,給出了介質(zhì)集成懸置線螺旋電感的電感值L、品質(zhì)因數(shù)Q、以及自諧振頻率SRF的經(jīng)驗(yàn)公式,加工的樣例電感的仿真與測(cè)試結(jié)果驗(yàn)證了整個(gè)建模過(guò)程。
[Abstract]:In recent years, RF microwave technology has greatly promoted the development of various industries. Miniaturization, low power consumption, low cost and high integration have become the main development trend of microwave circuits and systems. Dielectric integrated mount line is a new microwave transmission line system with excellent performance. It has the characteristics of low loss, low dispersion, low cost and self-encapsulation. However, the dielectric integrated mount circuit is self-encapsulated in the multi-layer circuit board, so it is difficult to directly test it. In addition, in order to integrate the transmission lines with different advantages into the same circuit, a highly integrated RF front-end circuit system is constructed. The microwave transition circuit with high performance dielectric integrated mount line to microstrip / CPW transmission line is one of the key technologies. Dielectric integrated mount circuit is a new design platform, but in the existing EDA circuit simulation software, there is no related circuit model, the design of dielectric integrated mount wire circuit still needs a lot of EM simulation. Therefore, it is more convenient and efficient to construct an accurate passive device model of dielectric integrated mount wire, and it can greatly promote the development and application of dielectric integrated mount wire platform. As one of the most important passive devices in dielectric integrated mounting line platform, the modeling of dielectric integrated mounting line inductor is one of the key problems to be solved. In this paper, a new type of dielectric integrated mounting line to microstrip / CBCPW transition structure is designed for different air cavity height and dielectric substrate material. The new dielectric integrated mounting wire microwave transition circuit can meet the test needs of the dielectric integrated mount wire circuit in the dc-25 GHz range, which lays a solid foundation and good guarantee for the development and application of the dielectric integrated mount line circuit. In this paper, a new type of dielectric integrated mounting wire spiral inductors and two dielectrically removed dielectric mounted wire spiral inductors are proposed, which can greatly improve the Q value of the inductors. In this paper, the systematic modeling of the dielectric integrated mounting line spiral inductor based on the dielectric integrated mounting line platform is presented, and its open-short parameter extraction method and physical base equivalent circuit model are introduced. The empirical formulas of inductance, quality factor Q and self-resonant frequency SRF of dielectric integrated mounting line spiral inductor are given. The simulation and test results of the sample inductor processed verify the whole modeling process.
