Lecture07: Impedance Matching with the Smith Chart

We can use the Smith Chart to perform inpedance matching. This lecture explains the matching using lumed elements as well as matching using transmission lines and stubs.

The step by step theory & math calculations directly identify the value of the required physical electronic components. This presentation of the circuit diagram & Smithchart effects genuinely helped my better understand the physics theory AND practical use of a Smithchart. Thank you !

[@therealtimwarren]

Thank you for this video! It has cleared up a lot of confusion for me. Very well explained.

[@goofypettiger]

Exceptionally clear and useful. Thank you.

[@healthbabe2691]

Hi Dr. Peik. Thanks for all your lectures with many examples in great details.

[@theodumbrovsky3239]

Great explanation! Really clear to comprehend!
Tks

[@leot7176]

This video is so helpful, you are my hero!!!

[@ravichandransrinivasan5453]

Very good explanation.Must watch several times and commit to memory.Thanks.

[@amiltonmanuelpensamento9832]

Thank you for explaining! I would like to see how you workout these problems in the non-ZY Smith Chart

[@maksymkloka7819]

Clarified a ton. Great video.

[@mehmetfurkanay9580]

Thank you very much for this lecture.

[@jorgerive7335]

very good explanation. Thank you

[@user-sajool]

thank you prof. From Polimi with all my respect :)

[@hamidk4772]

Excellent 👌👌👍👍👍

[@diarylee147]

Thank you so much for this wonderful video..

[@renatodias1804]

Very well explained!

[@mustaphaalkhafaaf5512]

Thank you Prof Peik , The more brilliant talented people I see who can explain things
the more I realise how rubbish lecturers are at most of the universities who
only care about the researches they do and their pockets

[@bou2222]

Thank you!

[@winstonalf]

Thank you for this. Please tell me how to convert Z value to actual capacitance and inductance.. for example: 10pF or 1.5nH

[@albinfetahu6411]

This video was helpful. Could you please add in description this smith chart please?

[@PatAutrey]

on the feedlines - are you using the velocity factor when making these calculations?

[@abfig78]

So I'm reading about attenuators and they say that sometimes they will use a low value to help with impedance mismatch.
So in ham radio, let's say my iCom 2m radio. Do they use one on the inside at all? Or is it simply up to using the proper antenna? Or probably there is some kind of matching circuit built in that is working for/with the proper antenna.
Idk. Just neat stuff. :)

[@user-su5sq5ib3i]

When you require high current you would always want series L and shunt C ?

[@user-ss3ol2ji5c]

Danke scho``n fu``r seine Videolektion, es hat mir sehr geholfen!
von seine russisch Studenten💙

[@aaronvanrossum2079]

Wait aren't the full circles a constant r and the other curves constant x

[@victorb22622]

Sir is there any simulator to find the matching stub value?

[@mohamedalzawam]

thanks

[@DMain-tb8ye]

Hard to follow when split view is on because I can not see the cursor and where he is pointing.

[@wridhdhisomkarar1633]

Where is lecture 8 ??? Please upload lecture 8

[@victorb22622]

Nicely described .for me ,it's 75:25 percent.i have to watch again.i guess from your teaching style that your are professor at college.so you might be doing/teaching student frequently.but, for student(age no bar to learn) like me it's tough to go with you. 😀,So, i must watch again.i came here ,because i have made SlimJim VHF antenna ,and want to tune it, but here you teach about transmission line impedance matching.so, coud you please simplify my case.

How do you find the values of admittance? I thought admittance was the inverse of the impedance. So wouldn't the admittance be either 1/100 or 1/50, how did you get 0.25?

[@user-kg7xn4ne7y]

Y=1/Z=1/(1+1.74j)=0.248-0.432j.

[@MrApolloTom]

How bad would it be to use resistors, compared to leaving things unmatched?

[@microwavelabcast2174]

Resistors may be an option. A resistor will match the amplfier, however, it introduces losses. The resistor match will not result in a higher gain as desired. Moreover, resistors add noise to the amplifier.

[@fenghc1]

Lecture 8, please. Thank you very much!

[@dariuskasen9229]

i realize I'm quite off topic but do anyone know a good place to stream newly released tv shows online?

[@scottomari1468]

@Darius Kasen Lately I have been using flixzone. Just search on google for it =)

[@philipjeremias451]

@Scott Omari Yea, I've been using FlixZone for years myself :)

[@dariuskasen9229]

@Scott Omari Thank you, I signed up and it seems like they got a lot of movies there :) Appreciate it !!

[@scottomari1468]

@Darius Kasen happy to help :D

[@mehmetdemir5655]

Smiss chart☺️☺️

[@user-zq3vq3ce6r]

hello , can someone please tell me how relevant is this job on the market ? , when I write micro wave engineer in linkedin i do not find many job applications maybe there is a different name to this ?

[@saintfather7757]

Unfortunately, there are no many jobs in this field.

Looks a lot like quantum physics to me.
