@@VEroselpro I hope the video was helpful then!

@MrSimEngineering the video is even more useful than what my teacher gave me🙏

Are you using an AXIEM EM set-up or Analyst? For most set-ups, you should be using AXIEM in single-sided mode which provides you an infinite substrate and ground plane so you apply the edge ports to the trace edges that will be your ports on the circuit. I would recommend watching my older series' EM tutorial since it really hasn't changed version-to-version.

If you are asking about the System Simulator, there is not much help I can offer you in the matter. My expertise is limited to the Circuit Simulator and EM Simulators within the Microwave Office suite. I would recommend seeing if there is an example file which can help you get started and adjust accordingly.

There is more to come in other regards to electrical engineering. Just need to find the time. Stay tuned!

I have not gone too much into the HB simulation side of Cadence AWR. I will look into it and see if I can possibly make this happen for you.

Thank you so much for your kind words.

If you mean the microstrip lines which allow the small footprint resistor to connect to the output lines, they are necessary in a real-world implementation of a Wilkinson power divider. I am sorry you failed in your exam due to the information in this video but the information is not incorrect by any means. This video was never intended to teach Wilkinson power dividers and only uses them as an avenue to teach the Microwave Office software. Seems your exam would like a more "ideal" microstrip implementation where these feed lines are not necessary to attach the resistor. I would recommend seeking videos specifically designed to teach RF content if you are looking for references to aid in your coursework. These videos are NOT reference material for the RF material itself and are ONLY to be used to learn AWR and REAL-WORLD implementations of the RF circuitry.

Without any specific details of your specific implementation of the design in the video, I would not be able to help resolve the issue. The question is vague as-written.

@@MrSimEngineering Thanks

Thank you! I got busy and haven't been able to finish it but I hope to get around to it soon.

That will depend entirely up to your use-case. If you're working in industry within the the USA, you will likely use mils (thousandth of an inch). If you're in academia or outside the US, millimeters (mm) and microns (um) are the way to go. Between um and mm, that will depend on the frequency space you're working within. I normally work between 1 GHz and 6 GHz so millimeter makes sense for me. Do a calculation of a half-lambda line (Half Lambda = c / (2f)) and see if closer to mm or um then choose the one best fitting for your application.

This is outside my area of expertise within AWR, but I will take a look at it if you still need it. If you don't need it, would you mind sharing here how you imported the model so others with similar questions can learn from your experience?

Hey Hasnain, thought I would reply again to let you know I will be taking an active RF course next semester so I may be able to finally make this video for you on transistor models.

Honestly, this is a great question. Despite Cadence AWR MWO being a great piece of software, a lot of its features and usability are hidden behind the paywall of their education programs and so forth. I am yet to understand why some parts of the characterization are linear versus non-linear. Like yes, I understand diodes are non-linear devices which can be behave quasi-linearly in certain circumstances. However, why does MWO approach this problem in this way? Mark Saffian handles a lot of the university educational license support stuff. Reach out to him at msaffian@cadence.com if you have specific questions about specific things in the software. Mark touched on this issue in an e-mail he sent me a while back which you can find the text of here ( pastebin.com/PmjpaT9p )

@@MrSimEngineering Thank you for taking the time to reply. I will try to contact the technical support regarding this. I have watched your EM simulation tutorials and tried to combine an EM simulation with the non-linear simulation of my diode however it is very tricky and there are results which I am not able to explain.

Thank you for the kind words.

Thank you for your contributions.

There's small buttons in the properties window which enable or disable entries and columns. Check them to make sure you didn't deselect the optimizer columns/options.

Thank you for the kind words, Rahul.

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).

Sadly I know nothing about active RF design in AWR. Maybe I'll learn someday and make a few tutorials.

please

Of course! Feel free to check the old series of videos I made back in 2019. The 2022 series will be trickling out throughout the Spring. Will be completely finished by the end of March since my students need it for their final project.

@@MrSimEngineering It'd be cool if you could follow what Anurag Bhargava does lock-step. Like for his Keysight ADS solutions to common engineer problems, do a Microwave Office one in tandem the same way he does it. Probably would get some good traffic, I know I'd watch! Thanks

Sadly I'm not active in the RF-IC space so teaching such would be outside of my skill level. However, if time allows, I might start looking into it.

What do you mean?

@@MrSimEngineering the "Di-electric layers" are defined as layer 1 and 2, right? one for Air and one for the Substrate . Why? And we do specify the Air thickness also in the Layer in Global definition in Di-electric Layer, right? Does it mean technically that Air's layer also to be considered for a certain thickness for the Impedance design? Did I ask the question in a right way ? Is it clear?

@@AmitKumarSahoo This is standard for microstrip design. The only situation where it would be different is if you are creating a suspended transmission line or you have soldermask as part of the fabrication specification. For a bare double-clad board, the side with the microstrip line will interface with air and this must be considered for proper simulation of the microstrip line. Feel free to read Chapter 3 of Pozar's Microwave Engineering to understand more about this. I should remind you that when we establish the wavelength for microstrip, it's the effective dielectric constant because half of the line is exposed to air and the other half is exposed to the dielectric material of the substrate. If not air, it's exposed to soldermask.

@@MrSimEngineering Thanks Mr. Anthony , this was really helpful in understanding the basics. I'm learning this new. Thanks again for the reference to the relevant chapter in the book as well.

@@AmitKumarSahoo I'll be discussing transmission line theory in a future series I'll be posting. Stay tuned for that.

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.

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.

Thank you! Stay tuned for the 2022 edition which will be coming out during this spring semester.

Thank you very much. There's going to be a 2022 version of this coming soon for V16 of AWR

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.

@@AmitKumarSahoo No worries!

You'd have to add some T-junctions and feedlines gapped according to your chosen SMD sizing.

I'm going to be making a 2022 version of the tutorials covering the new features of V16. Stay tuned!

You chose the wrong simulator. I used AXIEM in this example. Also, you may have the EMSight feature deactivated in your licensing manager.

@@MrSimEngineering thank you for the answer. Yes, ANXIEM works well, but I wanted to understand what was wrong with the EMSight. After many hours I just installed new version of MWO(15) and everything worked ok)

LSS is used for simulating S-parameters in the presence of active component models.

Thank you.

Thank you very much. There is more coming down the pipeline.

I'm a PhD student constantly tasked with designing, fabricating, assembling, measuring, writing, presenting, traveling, and a whole bunch of other duties. It can get a little hectic. I do LOVE making these tutorials and helping people learn great tools and cool concepts. It's comments like yours that push me to want to do more, more often. I was actually going to do one today about subcircuits and parametrized components but I botched it. Do wait for that one though! Again, thank you for the kind words.

Yes. Do make more tutorials frequently

This is super late, please forgive me. This is a simulator level error I've gotten in the past. Sometimes what fixes it is copying your design into a fresh, new project file. Sometimes reinstalling the program fixes it. Sometimes you have a problem in your design but if you're copying the video then it should work. I hope you were able to resolve the problem without my year-late response.

You're very welcome!

@@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

@@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.
