Thank you for that. Many ageing amateur radio enthusiasts like myself will likely be grateful for your very straightforward introduction to this black art.
I wish some one could force my lecturer to watch this video and learn how you teach an undergraduate student. Sometimes they seem to be teaching PhD students. Seriously... So frustrating. Thanks for the video. Saved me 3 hours of lecture with her/him. :D
I've been in RF since 1993. The longer I work in this field the less it feels like black magic, but also the longer I work in the field, the more I'm convinced its black magic. It all depends on what you truly understand.
@@eriknunezalbermann9993 It seems like in every interview I’ve had I was asked the formula for cascaded noise figure. 😊Of course research the company’s products as much as possible. What gets people hired is them being enthusiastic and passionate. I train people a lot. It takes about a year until they are independent. So they don’t expect you to get everything right. Brush up on the fundamentals. How do you add dBm + dBm? That was another question. Good luck!
Nice video. But how did you obtain the initial 50 +j50 load impedance values. Do you measure those with a scope in some way? I.e the resistance and reactive components of the load? I really would like to know exactly how you get those values from the physical load. Help!!
Good overview on how it works. But I still have a question. You said it tells "How well matched your load impedance is to the rest of the line - you could use the Smith chart." So now that we plotted those values - what do they tell us about that impedance matching? Thanks.
When somebody explains logarithmic scales, I wouldn't say that he missed the function of voltage dividers. It shows correctly how and impedance is calculated and how Z is found in a Smith chart.
I can plot all this no problem, but what do I do with it next? Is the goal to bring the impedance closer to the purely Resistive axis from a design standpoint? If I'm way out on the edge is the goal to design a network system that counteracts the impedance mismatch with hardware to say add more capacitance or inductance if your on one side or the other? sorry just a dumb mechanical engineer here who's just curious how to apply this. recently started working in RF and want to understand more.
You showed how to plot the complex impedance but didn;t answer the original problem: how well matched is the load to the characteristic impedance, is that expressed in dB? %? how much match is enough?
Hi sir, i have a question. I hope you can answer. This is the statement: you have a transmission line, when you have put your stub afar from load, you have a characteristic load and after the stub, you have a different charateristic load. How can i make the coupling?. Please, answer as soon you can.
thanks a lot it is a good video but i think the examples are pretty simple... u know in exams we're facing much more hard questions :/ so can you solve some difficult examples ???

this short video was better and easier to understand than my hour lecture + text book. it helped me finish my homework. thank you!
Thank you for this video. You made someone's life easier. God bless!
step by step tutorial, every thing is stable....so your info directly to my brain thank you
At first i thought you were very naive with pencil and paper, but this is actually pretty good!! Thank you very much! :)
thx a lot, you're explanation is so smooth and great, as they say : It takes a lot of work to make things look easy
make a 1080p
Very well.You are my teacher now..

Dude, respect. No matter how sofisticated Asians or European want to make it look, there´s no substitute for plain old American simplicity.
you just made my life much easier, cheers dude you a legend
you're great.... we need more good teachers in America
Thank you. You achieved to explain easily, what my teacher could not explain...
That's a must watch video! Wonderful job.
Many thanks. Clear, concise, and exactly what the title said it would be.
it helps a lot!! online learning is so hard and i have a test tommorow lucky me, i found this video
Carl, that was easy for me to follow! Thanks and keep up the good work!
Thank You Mr Simple and straight forward.
Brilliant.I dont know who you are but I must call you sir now
You, sir, are a lifesaver.
I dont know how to say thank you for your good work..........*1000000000thank you very much

Any tips to get an RF job? -Electrical engineer grad with antenna classes(:

Better than what my teacher taught
Thank u so much Carl Oliver, it helped a lot!
Thankyou soo much.. i have an exam tomorrow and this helped me a great deal..
god bless you you saved my semester and my finals thnx so much
thanks alot. all 3 part was excellent nd so much helpful .
love how u call me an expert fast :D thanks for the tut

wow!! its a great tutorial. you are a savior :)
Great video very easy to understand
Thanks! Explained simply and clearly!
thank you sir you saved my life
thank you sir! this is really gonna helpful for me
Thanks you have saved me in my EMFT paper:)
WOW, Excellent video!
brilliantly explained
Really appreciate it, thanks. It makes it easy to be understand XD
thanks, This Video helped me to understand the basics of Smith Chart :)
Enjoyed from Brazil.
Good overview on how it works. But I still have a question. You said it tells "How well matched your load impedance is to the rest of the line - you could use the Smith chart." So now that we plotted those values - what do they tell us about that impedance matching?
Thanks.
As long as the plotted point is near the prime center, means that is a good impedance matching .
Thanks Carl and RUclips, nice bro
Make video on stub matching
excellent video mate
you are god my friend, helped me a lot
god. really for showing a smith chart?
good*
Great video,
Much appreciated
I want to meet Mr Smith ! That dude was genius!
Thank you so much sir for sharing this knowledge...
The basics of a smith chart should include two things that were left out in this video. Inductance and Capacitance.
When somebody explains logarithmic scales, I wouldn't say that he missed the function of voltage dividers.
It shows correctly how and impedance is calculated and how Z is found in a Smith chart.
Excelent Video. Congratulations !
Well explain sir..Thank you so much 👌
Concise and precise, thanks!
Quick and easy!! Thanks!
thanks a lot, cannot be clearer than this.
Excellent! Thanks a bunch.
if you have a negative value on the the imaginary part of load impedance, the line matching the points should be downwards ?
Thank you, Carl!!!
Thank you sir very nice Explaination
thank you all the way from egypt
Excellent, thank you!
I can plot all this no problem, but what do I do with it next? Is the goal to bring the impedance closer to the purely Resistive axis from a design standpoint?

awsome video. thx bro!!!
Thanks..
you saved me!
thnk you sir....It was very helpful....
Samuel Liao! You managed to complicate such simple shit!Thanks for the video
You showed how to plot the complex impedance but didn;t answer the original problem: how well matched is the load to the characteristic impedance, is that expressed in dB? %? how much match is enough?
A 300 ohm transmission line is terminated with an antenna that presents a (450 ohm - j600 ohm) load impedance. What is the normalized load admittance?
Hey Carl , i am a little late to your channel :-) but what determines if its a - or + ? am i looking to hard ? cheers mate ! great tutorial 🙏
thnx man..really helpful..
thank you you saved my final
+DREAMWORKERSKY He saved my final too :'D
Great video thanks!
You are welcome!
awesome explanation
thank you sir
THAT CALCULATOR REVEALS EVERYTHING ABOUT EVERY TUTOR ON RUclips :p
Helpful sir..Thank you:D
Hi sir, i have a question. I hope you can answer. This is the statement: you have a transmission line, when you have put your stub afar from load, you have a characteristic load and after the stub, you have a different charateristic load. How can i make the coupling?. Please, answer as soon you can.
240P only?
No, you also have the option of 144P
Thank you so much bruhh!!!
In all the tests I've taken, Extra Class Amateur and commercial.
There was never a question about Smith charts.
thank u thank u so much ...!!!!!!!
plz also update the videos of electrical network als0
I subscribed sir,thankyou,😭😭
you saved me.. thanks
that pencil scribble sounds, tho. anyway this is great! thanks a lot for making this video!
una explicación rápida y sencilla, gracias :)
Thank you 😭😭😭😭
GOD bless you sir. Really. I mean it
thankyou, sangat membantu saya
Hhahha really good! Thanks🤙🤙
Helpful. Though when one needs a calculator to divide 300 by 50, or 25 by 50...
can you upload video about stub and double stub matching?
Great channel.. Glad I found you..EXCELLENT
Best regards/73,

continue like this .
thanks a lot it is a good video but i think the examples are pretty simple... u know in exams we're facing much more hard questions :/ so can you solve some difficult examples ???
Just keep going as if there were still a line there. In the video I go past R' = 2 at 7:16.
Man, I understand now!!!
OSM!! Tutorial sir...
realy helpful video.
saved me. Thanx:)
What if the Normalized R is negative?
Thank you sir.
