片上传输线用ADS Momentum哪种仿真模式？

12-08

帮助里写的，microwave模式好像更全面、准确一些，
而RF模式速度更快，但是substrate和space的
radiation effect不被包括。
如果想仿真衬底上的金属传输线，
是不是还是microwave模式更好一些？

看你的频段，help文件里好像是以3G为界的

3g以下RF，3g以上microwave？

About the Simulation Modes
With ADS 1.5, Momentum added an RF simulation mode to its existing microwave mode. The microwave mode is called Momentum; the new RF mode is called Momentum RF. Momentum RF provides accurate electromagnetic simulation performance at RF frequencies, typically up to 10 GHz; however, this upper limit depends on the size of your physical design. At higher frequencies, as radiation effects increase, the accuracy of the Momentum RF models declines smoothly with increased frequency. Momentum RF addresses the need for faster, more stable simulations down to DC, while conserving computer resources. Typical RF applications include RF components and circuits on chips, modules, and boards, as well as digital and analog RF interconnects and packages.
When compared to the Momentum mode, the Momentum RF mode uses new technologies enabling it to simulate physical designs at RF frequencies with several useful benefits. The RF mode is based on quasi-static electromagnetic functions enabling faster simulation of designs. The star-loop technology provides low-frequency stability down to DC. The mesh-reduction algorithms allow quick simulation of complex designs, and require less computer memory and CPU time. Additionally, Momentum RF has the same use-model as Momentum in ADS, and works with Momentum Visualization and Optimization. The following table shows how each mode supports Momentum product features. For a detailed comparison of the two simulation modes, see Comparing the Microwave and RF Simulation Modes.:
