需要帮助设计宽带4路威尔金森分频器之间的工作

您好Anum，您可以将ADS项目上传为归档项目（* .zap），而不是单个文件吗？
ADS 2011/2012可以阅读2009年的项目，但我不知道如何将您的单个ADS 2009文件导入ADS 2012.最好的问候Volker

  Hi Anum,

Can you upload the ADS project as archived project (*.zap), instead of single files?
ADS 2011/2012 can read 2009 projects, but I don't know how to import your single ADS 2009 files into ADS 2012.

Best regards
Volker

我已经以.zap格式上传了该文件。
问候。

  I have uploaded the file in .zap format.

嗨Anum，我设法将您的文件导入ADS2012，虽然翻译人员报告了一些丢失文件的问题（手动删除？）对于其他可能想要评论的读者，我附上了您的布局截图。
对于完整模型的EM仿真，我移除了顶盖并将其替换为开放边界。
正如您所报道的那样，我也看到传输是略微不对称的（~0.1dB），虽然布局看起来完全对称，并且EM网格中没有明显的不对称。
看起来真实。
我的解释是，这确实来自输出线之间的耦合。
它们都是同相的，但是相邻的线为“内部”线创造了与“外部”线不同的环境。
到目前为止，结果和方法看起来很好，有了最新的调整。
我单独模拟了两个阶段，这看起来很好。
隔离和输出匹配当然是关闭的，因为缺少电阻器。
为了更容易放置SMD电阻，您现在可能希望使用曲线或90°线段将布局更改为“环形”样式。
我附上了一个带有90°弯曲的旧设计的示例图片。
最好的问候Volker

  Hi Anum,

I managed to import your file into ADS2012, although the translator was reporting a few issues with missing files (removed manually?) For other readers who might want to comment, I have attached a screenshot of your layout.

For EM simulation of the full model, I removed the top cover and replaced it by open boundary. As you reported, I also see that transmission is slighty asymmetrical (~ 0.1dB), although the layout seems to be perfectly symmetrical, and there are no obvious asymmtries in the EM mesh. Looks real.

My interpretation is that this is indeed from coupling between the output lines. They are all in phase, but that adjacent lines creates a different environment for the "inner" lines than for the "outer" lines.

Results and method look good so far, with your latest tweaks. I simulated the two stages individually and that looks fine to me. Isolation and output matching are of course off as along as the resistors are missing. For easier placement of the SMD resistors, you now might want to change your layout to "ring" style with either curved lines or 90° segments. I have attached an example picture from an old design with 90° bends.

Best regards
Volker

非常感谢您对设计的详细分析和解释。
我肯定会在设计中采用这种戒指风格。
问候和祝福。

  Thanks a lot for your detailed analysis and explanation of the design.
I'll definitely adopt this ring style in designs i'll make.

Regards and best wishes.
