亲爱的，我在模拟薄膜电阻器时遇到以下问题。 Schematic，Momentum和FEM模拟器都给出了不同的结果。特别是：1-原理图给出了我期望的正确结果2-动量模拟似乎模拟了低于预期的电阻值。 3-FEM结果表明电阻器只是作为金属。请注意，我对所有模拟使用了相同的基板定义（原理图，动量，FEM）。有关所有详细信息，请参阅随附的ADS 2013工作区。任何人都知道如何解决这个问题？此致，Angelo编辑：apaglia于2013年10月31日下午2:18 以上来自于谷歌翻译 以下为原文Dear all, I have the following problem when I simulate Thin Film Resistors. The Schematic, Momentum, and FEM simulators, all give a different result. In particular: 1- Schematic gives what I expect as correct results 2- Momentum simulation appears to model a lower than expected resistor value. 3- FEM results indicate that the Resistor just acts as metal. Note that I've used the very same substrate definition for all simulations (Schematic, Momentum, FEM). Please refer to the attached ADS 2013 Workspace for all details. Anyone has got any idea how to solve the problem? Regards, AngeloEdited by: apaglia on Oct 31, 2013 2:18 PM附件test_thin_film_resistors_wrk.zip255.7 KB

您好，我阅读了以下在线文档，并对参考平面的物理偏移长度有疑问。 http://cp.literature.agilent.com/litweb/pdf/5989-4840EN.pdf我想设计同轴溶质校准标准，我不知道如何从短参考平面定义物理偏移长度并打开。我的频率范围从10 MHz到大约20 GHz，我希望在整个范围内平均回波损耗约为40 dB。可以使用以下公式计算我的长度：S11 = -e ^（ - j * 4 * pi * l / lambda），λ= c / fcenter如果我计算，我的长度约为8.8 mm。我的思考方式是对的吗？或者有人向我暗示我如何计算长度l？如果有人能帮助我，我将不胜感激。 以上来自于谷歌翻译 以下为原文Hello,I read the following online document and have a question about the physical offset length from reference plane. http://cp.literature.agilent.com/litweb/pdf/5989-4840EN.pdf I want to engineering coaxial solt calibration standards and I don't have an idea how to define the physical offset length from reference plane of the short and open. My frequency span is from 10 MHz to about 20 GHz and I want an return loss of about 40 dB in average over the span. It is posibble to calculate my length with the following formula: S11=-e^(-j*4*pi*l/lambda) with lambda= c/fcenter If I calculate, I get a length of about 8.8 mm. Is it right how I am thinking? Or has anyone a hint to me how I can calculate the length l? I would be grateful, if someone could help me.
