I know it is pretty hard. I just want to implement this equation using SDD component.
Ids = G*Vgs*exp(-jwt). With the circuit shown in my question it either throws an error saying a real value is expected at the SDD component or it doesn't seem to work as the output remains the same even though...
Hello
Could someone help me with implementing Ids in small signal model of HEMT using SDD component in ADS.

Hello
I would like to replace the VCCS by a SDD component in the small signal model of GaN HEMT(Using ADS). Could somebody help me in this? How many ports should the SDD be and what should be the equations?
Can anyone tell me how to optimize values for MSTEP, MTAPER, MTEE and other such design elements. Is it a trial and error method or is there a specific way to design for these like the linecalculator we have for other elements?
Yes I need 180 deg phase shift between the signals at port 2 and port 3. I also tried using a microstrip line(coupled) to do so. Here is the circuit for it. Can you please help me out in optimizing this?
The balun you have designed in the second attachment has S(2,1) and S(3,1) at -16 dB. Will it even transmit any signal at these values? I want S(2,1) and S(3,1) at -3 dB. Here is the design of the circuit I have done. Can anyone please tell me where I am going wrong?
I have designed a marchand balun with broad coupled strip lines which works perfectly fine but I want to use coupled microstrip lines in the design. Any idea how to transform the circuit below to use coupled microstrip lines?
Yes! That is what I meant. We have 2 lange couplers in the design. One lange coupler gives -90 deg phase shift to one of the signals and 90 deg to the 2nd signal and together they make up 180 phase shift between them.
Hello
I am designing a microstrip balun and plan to do it by using a Wilkinson divider to divide the signal into 2 signals with equal amplitude and then a Lange coupler to obtain 90 degree phase shift between the signals. The problem is with this design I am getting S(2,1) and S(3,1) more than...
