- 摘要:
- 为了消除由混频器非线性和非理想的隔离特性等因素引起的杂散响应,需要对混频器输出信号进行滤波处理, 将不需要的混频杂散信号滤除。而输出信号中的杂散响应又与输入和本振信号密切相关。因此为了减小后期电路 中对滤波器的压力,需要在混频方案设计之初,合理规划变频方案。混频方案设计人员迫切需要一个能在电路设计 前期对混频器所产生杂散信号进行预估计算的工具,而本软件正立意在此。软件基于.NET Framework框架,利用C# 语言,根据混频杂散产生的原理编写算法,对输入及本振信号进行多阶组合计算,并利用编程框架中集成
- Abstract:
- In order to eliminate the non-linear and non-ideal isolation characteristics of the mixer and other factors caused by spurious response, we need to process the mixer output signal to filter out the unwanted mixing spurs. While the spurious response in the output signal is closely related to the input and Lo signals we need to plan frequency conversion scheme reasonably to reduce the pressure on the filter in the later circuit. Mixing solution designers urgently need a tool that can predict the spurs generated by the mixer before circuit design, and so do this software. This software is based on.NET Framework and C# language with algorithms based on the generation principle of mixing spurious to calculate the spurious generated by the specified mixer Fin and Flo, meanwhile, real-time display by intuitive chart. We took the software maintainability into account in the process of programming and achieved the software features by using modular method and made it possible to update the follow-up function by reserve a lot of software interface. The software realized the basic functions by giving consideration to the ease of use and maneuverability. Engineers can calculate spurious signals generated in the mixing process before early program planning. It allowed getting the spurious frequency、amplitude and the rolling trends of spurious signals with the frequency changing by adjusting the relevant input parameters. It was said form some Front-line engineers that the software is not only fast but also accurate and eliminated the tedious but not rigorous calculations. The software also provides a trend of spurious changes in the presentation and made the result more intuitive and humane as opposed to some existing spurious analysis tools, that may after all be accepted as an innovation.
