| Nov 19, 2010 at 5:52 | comment | added | bjarkef | @Kortuk: 868MHz, in the ISM band (for Europe at least, "corresponding" ISM band is 900 MHz for US I think.). | |
| Nov 18, 2010 at 22:16 | comment | added | Kortuk | @bjarkef, what frequency are you at that you define as UFC. | |
| Nov 18, 2010 at 21:51 | comment | added | Kortuk | @bjarkef, Thomas is incorrect here, although they are both RF related, your applications are fundamentally different. I have done both, designing a trace to be 50 ohms is very easy, getting an RF generator to match can be quite challenging. | |

| Nov 18, 2010 at 19:34 | comment | added | bjarkef | Hi Thomas. I looked at your question, but I still do not understand how to actually measure what output impedance I have achieved, or how to design that in for that matter. Your question concerns the characteristic impedance for a transmission line. I am interested in the output impedance of a RF generator circuit (+ possibly the transmission line), and I don't understand how this relates. Please enlighten me? :) | |
| Nov 18, 2010 at 19:21 | comment | added | Thomas O | I asked a similar question about trace impedance: electronics.stackexchange.com/questions/5778/…. I think the answer is to design in the 50 ohms impedance, not to calibrate it after manufacture. | |
| Nov 18, 2010 at 19:20 | comment | added | bjarkef | Well, yes, I consider oscilloscopes in the hobby friendly zone. However I don't think a spectrum analyzer is in the hobby friendly zone, and I know any oscilloscope which has a high enough bandwidth to measure UHF and above (directly). | |
| Nov 18, 2010 at 19:09 | comment | added | Kevin Vermeer | Does "Hobby Friendly" include an oscilloscope? Also, do you wish to know the physical output impedance, or calculate the theoretical output impedance? | |
