Simulating Balun in ADS Schematic

Hello,

I am trying to do this circuit in ADS Schematic. I have been able to find all other components. But I have not been able to find this
"3 port Balun which says Balun_device". I did find other 3 port baluns, but I would like to know under which list it will be possible to find this component.
"balun_device" I have attached the schematic.

Please help me, as I have been stuck at this point. I would deeply appreciate it.

Thanks,
Prasanna

It is a custom component.

Select this instance and then do "identify" from menu.

Can you explain more? I would greatly appreciate it if someone explains and tells me how to simulate what is in the schematic.

Thanks for replying,
Prasanna

This schematic is on paper. I dont have a soft copy of the ADS program. Its from a thesis I am trying to implement.

First of all, do you understand an usage of Agilent ADS surely ?

See Balun3Port (Balun, 3-port) - ADS 2009 -*Agilent EEsof Documentation Center

Or see Fig.5 of http://www.designers-guide.org/Analysis/diff.pdf

Yes,
I am new to ADS. I did find the link you posted on the agilent website.
But is there a way, I can recreate the exact component as in the picture as in an exact way of simulating the custom component.

Thanks,
Prasanna

Again, can you understand an usage of Agilent ADS surely ?

that balun device is a subcircuit: inside that block there is another schematic and you cannot know from a paper what is inside.

Googling your infos, I've found this thesis:X-band Phase Shifters for Phased Array, Jean Xu, cincinnati university. Is it the one you are trying to implement, I guess.

The schematic of the balun is done using 2 lange couplers, see page 38.

I hope it can help.

Hi Mazz,

Thanks a lot, that explains it in detail.
Yeah I have downloaded that Thesis document and did see the schematic. So my understanding is that the "sub-circuit" inside this "custom component" is the schematic given in page no. 38.


Since I am new to ADS, i did not quite understand it.Thanks again.
How do i make my own custom component in ADS? Will it be possible for you to explain that?

Thanks,
Prasanna

I am sorry but I am not really sure what that question means..

you don't really need to do a subcircuit. You can place the balun at the same level of the rest of the circuit, if this is easier for you.
