You were right guys. Something is seriously wrong!
I have tried S-params simulation and I got terrible results with that ZL and ZS in hand! Hence I'd tried a somehow tricky simulation: changed the terminations Impedance on both side of the circuit till I get a notch on both S11 and S22 in the...
Yeah, I’m aiming for best PAE possible and the values that I talked about are all based On best PAE. My question is wheter the values are normal or not? 52 ohm for 75um device?
Hi everyOne!
first things first: I'm new to this stuff!
I'm trying to design an amplifer with a GaAs Design kit.
CAD : ADS
frequency = 1 tone 10.7 GHz
tried to bias it for Class A operation.
stabilized it.
now I'm trying to do load pull and source pull.
I'm just wondering to know the proper...
I did not noticed that you can read the both values at the same time. Interesting ! thank you for it!
So now we can say that each point on the smith chart simultaneously represents both a value of z and the corresponding value of reflection coefficient ! because if it was to just show the aho...
THESE ARE ALL WRONG! :bang:
Really! You are wrong. :bang:
you have posted a picture with no numbers on its axes!
I've done the exact thing as you've done ( even your naming :-D ) but with axis data VISIBLE.
look the attachment!
look at numbers. It's BOKE! NOT AHO!! :bang:
It is drawing the...
Z= 50 + j50
Z0= 50
normalized Impedance (z)= 1+j1
Gamma = (z-1)/(z+1) = 0.2 + j0.4
LOOK!
It's Obvious that Smith chart is not drawing the complex input it self! So what is it drawing?! Reclection coefficient
? no! see :)
Please Give it a try, And see. You are Wrong about what ADS is doing. I've Showed it exactly on the picture, Impedance is obviously visible on the chart, forget about the marker, I
TAKE A LOOK AT IT exactly! :) I've upload it with a better resolution
If you are not agree please show it on a...
what your said is exactly what I said !
you'r just naming normalized Impedance aho!
Surely you are yourself stuck with it a little. Every complex concept consist of very simple things.
It's correct what I just said. let's give it a try!
assume we have a Impedance: Z = 50 + j50
our...
Unfortunately it is not simply drawing any complex value that we are introducing as input! try it once.
I've figured it out.
It is true that smith chart is the ref coefs ( reflection coefficients) and smith chart in ADS will assume any input value as ref coef AND " will draw the normalized...
I'm sure that are you are right. But still with this definition:
I don't understand what ADS is drawing? Is it drawing ref coeffs? so where did it get the characteristic impedance?
Thank you for your time
Hi
I want to plot simple array of data in ADS smith Chart ( On display page , I\m not talking about ADS smith Chart utility).
Consider my load to be an array :
loads= [ 0.1::0.1::3]
My desired chart which is presented in one of keysight's tutorials must be like :
But I get this:
I know...
