摘要
随着现代通信和雷达技术的发展,毫米波的应用日益广泛,对毫米波频率源的需要也日益增加。本文由毫米波特点、毫米波源、毫米波倍频器的发展现状结合现实条件确定了使用倍频方式实现毫米波频谱输出的设计方案。
文章首先介绍毫米波倍频链的各分立部件的设计,其中包括Ka 频段宽带二倍频器、Ka 频段衰减器以及用于功率控制的耦合检波器和低频控制电路,然后连接各部件进行系统调试,控制程序的调试。设计中从各个部件的基本原理出发确定具体电路,再根据仿真、调试、测量结果修正电路。二倍频器选用平衡倍频电路,并内置微波放大器,实现了低输入功率要求、Ka 频段全波段输出;Ka 频段衰减器使用吸收管阵设计方式,使用两只PIN 二极管实现了方案所要求的功率衰减;功率控制电路使用键盘输入,LED 输出功率显示,单片机自适应控制,完成了输出功率可调的设计目的。基于以上工作本文按照毫米波对信号源的要求,着力于解决系统内各部件的相互协调,完成Ka 频段信号可调功率输出,实现了微波频率源的毫米波扩展。该倍频链在Ka 频段内8 个频段实现了输出功率在0-+17dBm 范围内可调,由于检波器的性能的原因未能实现整个Ka 频段功率可调。
With the developing of millimeter-wave communication and radar, the application of millimeter-wave is increasingly far-ranging, and the demand on millimeter wave source is on the increase. The dissertation firstly describes the property of millimeter wave 、millimeter wave sources and millimeter wave multiplier’s nowadays development at the first chapter, then confirms the proposal based on the realistic conditions that the multiplier fulfills the output of millimeter wave..
First of all, each of the components is introduced, which includes the design of the Ka-band wide band doubler, Ka band attenuator, the coupling detector and the control circuit that is used by the adjustable output of power. Then all components are connected and debugged. In the design, we firstly confirms the circuits of the components according to the basic theory, then corrects the circuits according to the result of simulating、debugging and measure. The doubler has been designed by the balanced circuit to achieve wide band frequency multiplying, uses preamplifier to achieve enough microwave power, and achieves the low input power and full waveguide band output. The attenuator has been designed by absorbing diode array, achieves the attenuation demanded using two schottky diodes. The circuit of power control has been designed by the input using keyboard, displaying using LED, adaptive controller using MCU(microcontroller unit), which achieves the adjustable power output. Based the above work, we can extend the frequency range of microwave signal source to millimeter wave band. The multiplier module achieves adjustable power output from 0 to +17dBm in Ka-band, but does not fulfills full waveguide band adjustable power output because of the performance of the Ka-band detector.
