Hi dear friends,
What means 1 sqrt (watt)?
In CST, it says the input signal scaling factor in waveguide port is 1 per unit of sqrt (watt).
What means this unit?
Thanks for help.
Hi.
I have a question, I hope maybe it is very obvious, so excuseme.
Always we are converting power in dbm format to voltage in for example, dbv format, we must know the system impedance.
In cables, or other media we can simply say about system impedance. 50, 75 and so on.
But in waveguide, we...
i forget to say that bad effect was because of L>(for example)5Lambda. consider 100mm at 28GHz.
but for Small Length like 5mm it was Ok.
Consider CST, Port Mode Information. the information was calculated even the whole circuit is defined. it is not necessary to open a new cst workspace and...
Thanks so very much dear volker, that works good.
I test it for a three layer stripline.
I check the effect of line's length and see that the plotted impedance of line has very changing value over freq.
Also I check this way in the whole circuit and see a similar behaviour.
Clearly, this way is...
Hi.
I want to see if my 50 ohms track in the stripline configuration has how much impedance.
Maybe it needs to tune the width of that track.
I know I can theoretically use ads line calc.
But is anyway to get the port impedance from Layout EM Environment?
Thanks.
i am agree with ge.
hyperthreading is not supported fully in cst, cpu usage in transient will never exceed real core capacity, then around 50% of cpu is implemented.
hi
can ADS simulate multi ports with simultaneous excitation?
consider a power combiner that i want to check what happens if i excite the input ports unevenly.
thanks.
I want to see the Loss effect of less conductivity for Metal electroplating on my laminate.
but i cant see any option in ads 2014.
can anyone help me plz?
when i create the component s111p (that n>99) with assistance of ads2014's help, and double click it, it doesn't open a properties window like for snp(n<99). for example i cant assign a data file to this data item and therefore i can not able to simulate it.
has anyone a suggestion?
thanks in...
consider a multimeter that we put the probes slightly on the surface of metal carrier without any pressure.
if the carrier has a good finishing, or it is a pure and good metal, the resistance measured by multimeter is a number for example under 1 ohm.
but otherwise, it may shown a number also...
what happens if i use a metal carrier that have about 2-3 ohm surface resistance (not ~zero) to fabricate a microstrip board on it.
it seems that one of bad effect will appear on signal loss...
can anyone describe it...
hi
i want to use a pc board connector (like sma type) on my pcb laminate to have a vertical interface.
how to solder the pin of a thru hole connector on my rf track?
best regards.
