RF Man Discusses Self Resonant Frequency of Capacitors and Inductors

RF Man Discusses the Self Resonant Frequency (SRF) of Capacitors and Inductors and talks about why this is important in RF design. Video shows why smaller capacitors are used for higher frequencies and larger capacitors are used for low frequencies. It also explains how inductors are used.

Thank you for your effort. It 's very clear to understand.

One big thank you for your video lessons ,greatly appreciate it ,thank you once again , peace and may GOD bless all.

RF Man, this is awesome. Thanks for taking the time to do these videos. W6MGV

[@rfmanchannel6915]

It my pleasure!!

[@DavidLopez-bz4rj]

Very interesting and very well explained, thank you!

[@rfmanchannel6915]

M You are very welcome. More videos to come.

[@TSulemanW]

Nicely explaination.

[@cheesedoodlefeeder]

thanks Rf man. to follow through, I would suggest doing a sweep of the 16:1 rf transformer 1 to 30 MHz used in your 2xLDMOS amp. best regards .

[@rfmanchannel6915]

Good idea. I will work on that!

[@szekerespista3758]

Sorry, i’m a beginner in electronics. Could you please clarify for my the following:
It would be an advantage to use a capacitor at his resonant frequency? (lowest ESR and lowest ESL).
Thanks!

Thank you for taking the time to explain all this. I think I am starting to understand. One question though, at 19:32 you said "inductive" and at about 20:07 you said "capacitive" (both points in the -J range). Did I miss something or did you mean to say "capacitive" at 19:32?

I already know Parallel and Series resonance frequencies from Bolyestad. But today I discussed a man about this subject. He said that Parallel SRF represents Cap or Ind bound from TL to ground as a shunt. I said no, I think Parallel SRF is like a capacitance of packet or wire bonding. Thank you for your explanation. I want to write this subject in my thesis. Do you suggest any scientific paper or book except Bolyestad about SRF? Do you have an article? I want to cite scientific articles.

One correction, I meant to say Milliohms for ESR not Millimhos. Thanks!

Hi , how to make fixture, which is error free

[@rfmanchannel6915]

You will never have a fixture that is "error free". For s parameters measurement, you have to "de-embed the parasitic effects of the fixture. If you keep the socket and lead lengths as short as possible, you will minimize the error. The accuracy is good enough for the frequencies we are working with......
