【摘要】：功率分配器是目前通信系统中不可或缺的无源器件,其主要作用是对功率进行重新分配和组合。功率分配器广泛应用在功放电路、混频器、预失真电路以及MIMO天线等通信领域中。传统的威尔金森功分器由于其工作频率和带宽的局限性,已经无法适应目前通信系统的工作条件。首先,本文简单的对功分器的研究背景作了介绍,对双频功分器及宽带功分器的研究现状作了重点的阐述。其次,本文详细介绍了威尔金森功分器和阻抗变换器的特性以及原理,对双频功分器和宽带功分器的设计原理进行的深入的分析。在基于传输线理论和电磁场微波理论基础上,提供了新型功分器的具体设计方法和理论参数。然后,依据功分器的具体设计参数,在ADS仿真软件中分别建立了工作在双频和宽带的两种类型的功分器模型,并利用ADS软件对其进行了仿真分析,在AutoCAD中设计制作了功分器的电路版图,并完成了不同类型功分器实物的制作加工。最后,利用网络分析仪对新的功分器实物进行了性能测试,并对仿真结果和测试结果进行了对比分析,结果证明本文提出的2种不同类型功分器设计方法是正确的。本文提出的新型功分器具有小型化,结构简单等优点,能够满足当代通信领域对器件的要求。
[Abstract]:The power divider is currently an indispensable passive device in a communication system, its main role is to re allocation and combination of power. Power divider is widely used in power amplifier, mixer, predistortion circuit and MIMO antenna in the field of communication. Conventional Wilkinson power divider because of the limitation of working frequency and bandwidth, has been unable to adapt to the current communication system working conditions. Firstly, the research background of this paper for the simple power divider is introduced, this thesis expounds the research status of the dual frequency divider and broadband power divider.
Secondly, this paper introduces the Wilkinson power divider and impedance converter characteristics and principle, in-depth analysis of the design principle of the dual frequency divider divider and broadband power. Based on the theory of transmission line and microwave electromagnetic field theory, provides a novel power divider with the design method and parameter theory.
Then, according to the specific design parameters of power divider, in ADS simulation software were established in two types of dual band and broadband power divider model, and carries on the simulation analysis by using ADS software, the design of circuit layout made power divider in AutoCAD, and finished the processing different types of power divider real.
Finally, the performance of the new power divider is tested by network analyzer. The simulation results and test results are compared and analyzed. The results show that the 2 kinds of power divider design methods proposed in this paper are correct.
The new power divider presented in this paper has the advantages of miniaturization, simple structure and so on. It can meet the requirements of modern communication field to the device.
