"Electronic applications of the Smith Chart in waveguide, circuit and component analysis" Phillip H Smith It's not on archive.org

Smith Chart lovers: A few months ago I downloaded a free copy of Mr. Smith’s book. I have mislaid the URL. Keep looking. I am sure you will find it. Chuck KF8TI

Again, that's why SimSmith is an indispensable tool when dealing with complex impedances and over different frequencies. It is a universal presentation tool in the professional RF and microwave world.

And I say that if we represented the Smith as attached, it would be much clearer. This is also how we project impedances on the Smith. It has, in addition, the great interest of materializing the S11

hi HO-Ro - thanks for the reply. Currently with the firmware of dslord 20211230 it works for me (I also noticed that it has many new parameters,) I was wondering if this firmware was the ideal one,

No problem.. The whole "uncertainty analysis" for a VNA can be remarkably complex - people spend their entire life researching it, getting a PhD along the way. If you think about something simple,

Roger, you make an excellent point. I would however like to point out that I believe your 100 +j0 and 25 +j0 are swapped. 25 should be on the left side and 100 should be on the right side of the

Thank you very much for this explanation. To say that I understand everything would be inaccurate but I now understand the principle. I will integrate your text (in French :)) in my summary document

sure.. The way the NanoVNA receivers work is by taking the input signal and mixing it with a LO that is 5 kHz away and doing an analog low pass filter. That audio 5 kHz signal is fed into a standard

As long as you tell the calibration algorithms the impedance of the 3 test loads, then it doesn't matter a whole lot. There are better and worse values, of course, but ultimately, it's a "solve three

Hi Roger, This is an (educational) presentation, not a paper. My talks are always for radioamateurs and this formula is best known. This triggers the audience to listen before it gets more

Hi, I have the same HW as you and update the FW regularly with the latest DiSlord versions. His project is very active and brings a lot of improvements: https://github.com/DiSlord/NanoVNA-D It

Hi all, in April 2020 I purchased a NanoVNA H with the following characteristics: https://github.com/hugen79/NanoVNA-H Based on edy555 design Licensed under GPL see https: // etc ect Version

Hello I follow your discussion with interest but my language is not English - thank you Google. If you could avoid using acronyms such as "ADC". What does it mean ? Could you develop a little more

Yes of course, the ohmic, or DC resistance itself in the context of the antenna impedance measurement?is a far less significant contributor than the reactance's; capacitive, and inductive. But, in

You are thinking in DC, switch to AC + calibration plane, fringing capacitance etc. [email protected]> wrote:

I got my cal kit from Dr. David Kirkby kirkbymicrowave.co.uk. It includes not only extensive characterization data but also optionally verification standards which will allow you to check the quality

That is NOT a calibration board. That is a DEMO board. Those are good enough to show a VNA newbie: What would a parallel resonant circuit look like on a VNA? What would a series resonant circuit look

Sure - the original question was about possible other VNAs with better performance. I cited the Keysight FieldFox (an "inexpensive" analyzer in Keysight land :) ) as I interested in showing how they
