Re: plz help
Let us suppose that you have three metal layers, and you map them to pc1, pc2 and pc3. If pc1 is the TOP ground plane and pc2 is the bottom one, you need two layers of vias to interconnect them, one going from pc1 to pc2 and another going from pc2 to pc3. So you will copy your...
Re: plz help
Hi,
in Momentum layout window, first of all you must draw your hole. Chose a layer (for example the "Hole" layer) and draw it. Depending on the frequency, and on the amount you have to simulate it, you may want to draw it circular or poligonal. Most of the time, a square cross...
Hi all,
for my job I developed some programs/scripts to compute the dimensions of some planar microwave structures. I then simulate them under ADS2009 using Momentum.
As those structures are quite complex to draw, I would like to avoid the manual design procedure, that is extremely time...
Hi everybody,
I need to do an EMI/EMC simulation on a design that includes a Smart Card (SIM) connector. I am planning to use either HFSS of EMPro for the task, but it is extremely difficult to draw the model of the connector itself in an accurate way.
Does anyone has a mechanical or 3D EM...
Yes, the problem with HFSS is that, first, you have to really know how you are going to define ports, while in ADS it's a bit simpler (but you can have odd results as well). Second, drawing on HFSS is quite complicated, and I would say impossible above some degree of complexity. It's always...
I did the same error in the past ;)
About ADS, it is quite easy to design microstrip subassemblies, as you have parametric models in the schematic window. You connect them, and you can even tell the optimizer to tweak the design dimensions to have a given performance. Then, once you are...
Well,
first I have to say that I am a newbye on HFSS. I am curious about your waveport definition, what was wrong with it?
On the BPF, HFSS is not the right tool to design it. Or, better, it is not a good idea to begin from it. I would start from a circuit simulation, using ADS or Designer...
I observed a similar behavior, but even Agilent support was not able to explain why this happens (by the way... have you contacted them?).
What version of ADS/Momentum are you using?
