【摘要】：近年来,射频微波技术极大地促进了各行各业的发展,小型化、低功耗、低成本、高集成度成为微波电路与系统的主要发展趋势。介质集成悬置线是一种性能非常优良的新型微波传输线系统,其具有低损耗、低色散、低成本、自封装等特性。但是介质集成悬置线电路自封装于多层电路板内部,难以直接进行测试,此外,为了将具有不同优点的传输线集成在同一电路中,构建高度集成化的射频前端电路系统,因此,高性能的介质集成悬置线到微带/CPW等平面传输线的微波过渡电路是研究的关键技术之一。介质集成悬置线电路是一个全新的设计平台,但是在现有的EDA电路仿真软件中,没有相关的电路模型,介质集成悬置线电路的设计仍然需要进行大量的EM仿真。所以,构建精准的介质集成悬置线基本无源器件模型,不仅能够更加方便、高效地进行介质集成悬置线电路的设计,同时开可以极大地促进介质集成悬置线平台的发展与应用。介质集成悬置线电感所以作为介质集成悬置线平台最重要的无源器件之一,其建模是亟待解决的关键问题之一。本课题针对不同的空气腔高度和介质基板材料,设计了新型的介质集成悬置线到微带/CBCPW的过渡结构。新型的介质集成悬置线微波过渡电路能够满足dc-25 GHz范围内,介质集成悬置线电路的测试需要,这为介质集成悬置线电路的发展和应用奠定了坚实的基础和良好的保障。本课题提出了新型的介质集成悬置线螺旋电感,以及介质挖除的双边走线介质集成悬置线螺旋电感;这两种新型的电感能够大幅度地提高电感的Q值。本课题对基于介质集成悬置线平台的介质集成悬置线螺旋电感进行了系统化的建模,并介绍了它的open-short参数提取方法以及物理基等效电路模型,给出了介质集成悬置线螺旋电感的电感值L、品质因数Q、以及自谐振频率SRF的经验公式,加工的样例电感的仿真与测试结果验证了整个建模过程。
[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.
