Hi,
I'm simulating a rectangle or circular PEC plate in EMPro to calculate the RCS.
When the frequency of operation is 6 GHz and the dimension of the place is about twice of the wavelength (wavelength=50 mm at 6 GHz and the dimension is 100 mm) the RCS is about -2~-3 dBsm
But when I increase the...
Dear Friends,
I am simulating 2-cascaded snp block with transient simulator in ADS and then using s-parameter simulation I convert the 2-cascaded block to a single block and then run the same transient simulation for this block.
The problem is that the simulation results are not the same in...
I simulated s2p file in transient simulation but according to the document I have attached but because of problems of causality and passivity, agilent suggests it is better to use Impulsewriter. I simulated it in transient but the results were not reasonable. What do you suggest?
Dear Friends,
I have gotten an "impulse response" for my s2p block using impulsewriter.
Now I need to apply this impulse response to my circuit to find voltages and currents of a step-function source. How can I do that? which simulation do this? how can I read this .imp file to a component in...
Hi Dear friends,
I have a homework and I can not figure out how to do that. I'm so stressed. May you can help.
I have a moving charged particle placed in electrostatic field of E0 and magnetostatic field of B0. There is no radiation from a large volume surrounded the charge. Now I need to find...
Thank you so much, I will read it and if I have furthur question I will ask you.

Dear Pancho
I searched but I didn't find how we can build a FIR filter from S2P file and also how we can use it to perform transient analysis.
Would you please explain a little more about the...
Dear Friends,
I am simulating a schematic in time domain (transient simulation) which includes a block defined by a s2p file.
I need to figure out what kind of algorithm(equations) ADS uses to extract the results in time domain?
Thanks in advance
Hi,
I'm simulating a grounding s-parameters.
Till now I had simulated antenna and filters that have 3 layers at least but now I have just 1 layer and ADS-momentum gets error for one layer and without substrate. Does anybody knows how to define the one layer conductor in momentum.
I need a...
Hi,
I want to simulate a power cable in low frequencies (less than 100 MHz) using the RLGC file which I have made in Matlab.
I don't know how to change my RLGC file(my current RLGC is freq, R, L,G,C for 200 frequencies). Is there any of you have done this to send me your simulation file to make...
Hi,
I have a s2p file of measured transmition line with network analyzer. I have 2 questions:
1- How can I read this file in Matlab
2- How can I convert it to ABCD file? I have a m-file that uses the function of s2a(S) but I don't know how to define (S)?
3- How can I transform this ABCD to RLGC...
Thank you for your kind reply
I need to design a filter whose center frequency is on 160 MHz.
At your sent file the maximum frequency was at 10 MHz.
So I have a more question : Is this method is applicable to aforementioned frequency(160MHz)?
May I design an active filter at lower frequencies...
