Tutorial-63: De-embedding in ADS

[@asifsurti9154]

Thank you. It was very good explanation and easy to understand.

Glad it was helpful!

Another great video like always

Glad you enjoyed

Should I do the same for differential signals, just with setting the measured equation SDD11 as 0.5 * (S(1,1)-S(2,1)-(S1,2)+S(2,2))?

[@BhargavaAnurag]

for differential circuit, you can simply use Balun at input and output to avoid writing detailed equations.

Hi Sir, I need to deembed the signal while running on transient sim but ADS has no option to use deembed while on Transient Sim.I have converted S parameters to T parameters and wish to use T parameter and its inverse to get the original deembeded signal.Could you let me know how T parameter model can be inserted back in the schematic.I see S,Z,Y port models but no T port model to be placed in the schematic.Thanks

The question you asked can be pretty involved topic hence I would recommend you to contact your local Keysight tech support team for help.

perfect, thanks

Sir, I would like to ask how to find the loadpull template that can show the second harmonic PAE contour from the ADS design guide. I still can’t find it after searching for a long time...🥲

[@jeffhou2125]

Can you make a video to talk about this, or leave a message here? thank you for helping me.

[@BhargavaAnurag]

There is a parameter on the LoadPull Instrument: Swept_Harmonic_Num which set to 1. You can change this parameter to whatever harmonic index you want and then make sure you use the appropriate S_Load.....on the desired harmonic

[@jeffhou2125]

@@BhargavaAnurag Thanks for replying, so...do you mean that if I want to consider second harmonic now, I need to set Swept_Harmonic_Num to '3' (note shows Z_Load_3rd will be ignored), then the 'PAE_contours_Rho' from the simulation results page will be represented in the second harmonic PAE contour? I don't really need to construct a new equation to find it right?

[@BhargavaAnurag]

Hi Jeff, If you set Harmonic number to 3 then you need to set Z_Load_3rd to desired impedance and the area selected in the Smith Chart will be swept and all the data reported in the DDS will be for 3rd harmonic without you needing to do anything. If you need further help then you should contact your local Keysight tech support team for assistance.
