Important correction for the video: The resistor value should NOT be set to 2*Z0 as Z0 is the physical width of the transmission line and not the actual impedance value of 50. You have to set the resistor to 100. It did not matter much for the power division but the isolation between ports 2 and 3 suffered as a result.
Hello, Thats a really amazing video. Will you please upload more videos like that using AWR like designing of couplers, phase shifter, Impedance transformers etc..It will be really helpful for students like me to understand RF.
@@MrSimEngineering Hi Anthony: Do you have a video showing how a nonlinear circuit, such as a PA, is simulated and results of two tone test is displaced in frequency domain? Thanks. Steven
Because the arms have a section before the bend and a section after the bend. The first section before the bend is 1 / 8 and the one after is an 1 / 8 for a total of a 1 / 4.
Around 10:56, in txline I show how to synthesize the necessary physical length for an electrical length of 180 (half lambda). That length was placed in the HALF variable (because it's HALF-lambda or 180 degrees electrical length).
AXIEM is covered in Part 3 of the tutorial which is already available on the channel. I cover how to extract from a circuit to produce a 3D EM simulation using AXIEM. If you mean how to natively do your designs in AXIEM without using the circuit designer, there are currently no tutorials from me on this matter. Though if it's requested enough, I can consider taking the time to learn how to do it for a specific use case and teach it through that lens.
I have Lab exercise where instead of GaAs (Gallium Arsenide) I'm supposed to use FR4. Could you please tell how to make a new substrate like FR4 come there manually? Thanks in advance
Under the components, you're looking for the MSUB component. Once you drop it in, you can change the settings to whatever your lab is asking for (FR4 or otherwise). Let me know if you need more help.
@@MrSimEngineering Hi thanks . Our lab demonstrators told us to use GaAs itself as the substrate. It's just the name that we can re-name as FR4. Thanks anyways. I have another urgent doubt :- - How to use the Tune bar to see real time changes in the graph , after setting global definitions . I tried to tune the width of the conductor (setting it as the tuning parameter in the global definition), and see the changes in the Z (Y-axis) w.r.t Freq. (X-Axis) I'm a current student in University of Glasgow and new to this software and subject.
@@AmitKumarSahoo You will have to be observing a measurement in the Graph view. You can then hit the Tune button (i.imgur.com/okCtHqT.png) in order to pull up the tuning window. As you shift the value around, the simulation should re-run and update the graph accordingly or prompt an error. I will remember to address manual tuning in the new 2022 tutorial series I will be doing to replace this 2019 version.
@@MrSimEngineering Hi thanks. I actually found my error. I hadn't inpnut the variables from Global definition in the circuit schematics and was trying to tune directly in the graph. Sorry. 😅 I got the real time changes now. Thanks a ton for your prompt responses.

Thanks! Great AWR tutorial. Clear explanation with good video editing.
A well prepared presentation provides a clear path to start a project. Appreciate it !
You're very welcome!

@@stevenliu2093 I do not, but I could look into it and see if I can put together a video which answers your question.
@@MrSimEngineering Thanks. when life is back to normal, it may be a better time for you to share your experience. Stay safe and healthy.
This was very useful. Thank you for explaining so clearly!
Very nice presentation!
Thank you very much. There's going to be a 2022 version of this coming soon for V16 of AWR
very awesome great please share more videos
Thanks a lot!
Great Tutorial!
Thank you! Stay tuned for the 2022 edition which will be coming out during this spring semester.
The two branches are lambda/4 wavelength then why are we using L=Quarter/2. I did not understood that part.
Because the arms have a section before the bend and a section after the bend. The first section before the bend is 1 / 8 and the one after is an 1 / 8 for a total of a 1 / 4.
@@MrSimEngineering thank you for the clearification.
@@deepanshutrivedi2536 You're very welcome. Let me know if you have any other questions.
I didn't understand how you calculated the value for the variable "HALF". Can you elaborate on that?
