基于交叉耦合的介質加載雙工器設計
[Abstract]:With the rapid development of mobile communication technology and the increasing shortage of communication frequency resources, the role of microwave filters, Duplexers and other microwave passive devices has become more and more important. Because the performance of microwave filter has a vital influence on the quality of the whole communication system, our requirements for its performance index are getting higher and higher. Therefore, the development of small size, high performance and low cost filter in a short time has become the key technical requirement of the current research filter. Cavity filter has been widely used because of its small size, high performance and easy realization. At the same time, microwave ceramic dielectric materials are also constantly developed and applied in cavity filter. In this paper, the cavity filter is deeply studied by using the basic theory of cavity filter and dielectric resonator. A coaxial cavity filter and dielectric cavity filter are designed respectively. The performance of the two cavity filters is compared, and the power capacity estimation and temperature drift simulation of the cavity filter are briefly described. Based on the above design and research, a set of methods for fast design of cavity filter by collaborative simulation of various software is summarized. On this basis, a ceramic dielectric Duplexer in WCDMA band is designed, and the effectiveness of the method is verified by an example design. The Duplexer designed in this paper is novel in using dielectric loading and introducing cross-coupling between cavities. The microwave ceramic dielectric material with high quality factor greatly increases and reduces the insertion loss of the cavity without load, and introduces cross-coupling between cavities to reduce the number of cavities and improve out-of-band suppression, which realizes the miniaturization and high performance of the devices, and has remarkable advantages over the coaxial cavity Duplexers in the same frequency band.
