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.
this channel helped me so much 2 years ago for my HF engineering module learning and applying smith charts to solve impedance matching network problems, thank you so much!
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 !
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
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.
9:00 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?
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. :)
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.
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 ?
