Hello Klaus, Yes you are tottaly correct i will try to focus.
From the datasheet of TGA2590 drain source resistance of the power amplifier is 20/6=3Ohms.
But my spice model is not logical.
How do i simulate the mosfet power amplifier anddriver together?
Thanks.

Hello , There...
Hello , I have built a unit cell wich intend to do beam steering using phased array theory.
So basicly i think of a unit cell as a "patch antenna".
my "patch" has two resonances i could tune.
Each resonance has its own phase as shown below.
the first resonance is at 0 degrees .the second...
Hello, I am looking for a metagrating unit cell , could be a slot or a wire in which i could radiate plane wave on it and extract the surface impedance from it ,in CST.
I woud like to match the CST result with analitical formula.
Is there any manual i could use?
Thanks.
Hello , I am trying to recreate the impedance of a unit cell of the table shown below from the attached link using CST.
I have shown a step by step of how i tried to extract the impedanceof the cell.
Is there someone who done it before and could help me understand teh proccess...
UPDATE:
Hello ,according to the datasheet I have to put 20V on the drain of the TGA2590 power amplifier that means i need to put
20V on the source of the mosfet.
You said that its a floating voltage without reference ,how do i make sure i have 20V on the source of the mosfet (drain of TGA2590)...
Hello Volker, the S11 S12 of each resonator is shown apart. I know that i somehow need to look for the resonanceswhich are in teh resonantors themself any intuition how to find them?
Another question is how exactly this structure could be used for ? of connecting two resonators in series...
UPDATE:
Hello , I have simulated an identical device gate driver shown below.
As you can see my output pulse moves from VDDA to VSSA .
If this is going to a mosfet then i need to know what voltage goes into the the MOSFET.
given that DB02s2415A is that source of my driver how do I know what...
Hello Volker,When i have designed those resonators i saw the desired modes.
And i still see them but compared to the coax line the field of the resonator are very weak.
So i will try and tune the first resonantor and i will see the field stronget then the coax?
maybe because the distance...
Hello I want to simulate UCC5340 but I was told that there is none and that i should use UCC21220A instead.
from datasheet section 6.9 i made the following connection.
Ho do i see in the datasheet what kind pulse i need to put into the device?
Thanks...
Hello , I am just learning the principles of the circuit so i could simulate and understand how it works.
I have two questions:
1.What is the exact voltage of -Vout(Viz) and +Vout(Giz) given the data sheet. In the photo shown below they say 15V but its not enough because i need to know the...
Hello ,I am used to this of voltages always with reference to some poing gnd.
When we want to mosfet to be ON we have to put at least 10V Vgs.
we have DB02S2415A which gets as input 24V and -12V while the output is Viz and Giz which are refrenced to gnd of the supply of the component.
Then those...
Hello Klaus,I imagine the path of the current as shown in the red arrow.
J4 has tottaly other reference "GROUND" ,J4 is supposed to be the connection to the drain of TGA2590 amplifier.
You are tottaly correct that i miss schematics data and i will try to find it.
But this is tottaly new to me...
