摘 要

本文介绍了毫米波的特点，根据构成毫米波倍频器的不同器件，介绍了不同毫米波倍频器的实现方法，综述了毫米波倍频器这一领域的研究水平及其发展动态，重点研究频段全波导带宽倍频器的设计方法，从而将波段信号扩展到波段。根据目前的研究水平，采用肖特基势垒二极管作倍频元件没有带宽的限制，这是设计全波导带宽倍频器最有前景的一种方法。通过对各种倍频方案进行比较，最终确定了采用平衡式电路结构。六倍频源应用广泛，比如电子设备、控制器等行业，都会运用到六倍频源系统或工具。更高效率和更高精度的六倍频源一直是研究的热点。在我们日常生活中，六倍频源随处可见，因为其相比其他的控制方式而言，运行稳定且控制精度较高等优势。随着自动控制技术和微电子技术的不断革新，目前的技术水平为实现六倍频源调节控制打下坚实的基础，提供扎实的理论依据。

通过倍频方法和功率合成方法设计了W波段六倍频源，将Ku或K波段信号倍频至W波段。信号经过Ka波段二倍频、巴仑、有源放大后，输出两路信号功率约为25dBm，以此推动变容肖特基二极管进行三倍频，并进行功率合成输出。为了抑制偶次谐波和提高输出功率，二极管使用了反向并联平衡电路结构。该六倍频源在50～75GHz输出范围内输出功率2-8dBm、最大输出功率为8dBm。该模块提出了W波段源的产生方法，为今后设计W波段TR组件发射源提供了参考价值。

本次设计主要以六倍频源控制系统设计应用作为研究背景，运用MATLAB仿真工具搭建相应的仿真模型。该模型利用MATLAB软件中的模块库，建立了六倍频源在电力系统应用中的系统仿真模型，通过 Matlab仿真软件搭建仿真模型,运行仿真，并对六倍频源的仿真结果进行了分析。

Abstract

This paper introduces the characteristics of the millimeter wave, according to the different components of a millimeter wave frequency multiplier, this paper introduces the method to realize the different millimeter wave frequency multiplier, millimeter wave frequency multiplier is reviewed the research of this field level and its development trends, key research spectrum design method of the waveguide bandwidth frequency multiplier, broadening the band signal to the band. According to the current research level, schottky barrier diode is used as frequency doubler without bandwidth limitation, which is the most promising method to design full waveguide bandwidth doubler. By comparing various frequency doubling schemes, the balanced circuit structure is finally determined. Six times the frequency source is widely used, such as electronic equipment, controller and other industries, will use six times the frequency source system or tools. Sixfold frequency sources with higher efficiency and accuracy have always been the focus of research. In our daily life, six times frequency source can be seen everywhere, because compared with other control methods, it has the advantages of stable operation and higher control accuracy. With the continuous innovation of automatic control technology and microelectronics technology, the present technical level has laid a solid foundation and provided a solid theoretical basis for the realization of six-fold frequency source regulation and control.

A w-band sixfold frequency source was designed by frequency doubling method and power synthesis method, and the Ku or K-band signal was doubled to W-band. After the signal is amplified by Ka band double frequency, Barron and active power, the output power of two signal channels is about 25dBm, which drives the variable schottky diode to triple frequency and synthesize power output. In order to suppress even harmonics and improve output power, the diode uses a reverse parallel balancing circuit. The sixfold frequency source has an output power of 2-8dbm in the 50-75ghz output range and a maximum output power of 8dBm. In this module, the generation method of W band source is proposed, which provides reference value for designing W band TR module transmitter in the future.

This design mainly to six times the frequency source control system design and application as the research background, using MATLAB simulation tools to build the corresponding simulation model. In this model, the module library of MATLAB software is used to establish the system simulation model of six-fold frequency source in power system application. The simulation model is built by MATLAB simulation software, and the simulation results of six-fold frequency source are analyzed.
