布局组件的谐波平衡模拟选择顺序是什么样

大家好！
我有一个布局组件，我用ADS动量uW模拟，它包含我的电路的金属层，然后我在电路上执行HB sim。
假设我的基频是10 GHz（感兴趣的频率）。
最初我模拟了从5到15 GHz的动量，但我的结果不是我预期的，所以我模拟了高达20 GHz并且得到了更合理的东西。
我假设这是因为HB没有“看到”模型中的任何谐波频率？
这引出了我的第一个问题：这是否意味着我需要在动态范围内执行S-param仿真，直到HB sim中指示的顺序？
例如，如果我对HB使用order = 9那么我需要模拟高达100 GHz的布局以获得逼真的结果？
这对我来说似乎是合理的，但是对我来说模拟这些高频是不太实际的，因为我的端口的+和 - 端子之间的距离变得超过20 GHz左右。
尽管如此，即使我只模拟高达20 GHz但使用更高阶的HB sim，我得到“更平滑”的结果，但ADS在这些更高的频率上从哪里拉数据？
这些结果可以信任吗？

  Hello everyone!

I have a layout component that I simulated in ADS momentum uW which contains the metal layers of my circuit and then I perform a HB sim on the circuit. Let's say my fundamental frequency is 10 GHz (the frequency of interest). Initially I simulated in momentum from 5 to 15 GHz but my results were not what I expected so I simulated up to 20 GHz and got something much more reasonable. I'm assuming this is because the HB did not "see" any hARMonic frequencies in my model?

That leads me to my first question: Does that mean that I need to perform an S-param simulation in momentum up to the order indicated in the HB sim? For example if I use an order=9 for the HB then I would need to simulate my layout up to 100 GHz to obtain realistic results? This seems reasonable to me but it's not very practical for me to simulate up to these high frequencies because then the distance between the + and - terminals of my ports become electrically large past 20 GHz or so. Still, even if I only simulate up to 20 GHz but use a higher order for the HB sim I get "smoother" results but then where is ADS pulling the data from on these higher frequencies? And can these results be trusted?
