Absolutely not!!!!!!!!!!!!!!!!!!
He needs best possible loaded Q for maximum selectivity! Good unloaded Q will help minimuze circuit losses, but won't help with selectivity. Joe W3JDR "Airy R. Bean" wrote in message ... Then it is unloaded Q that you are interested in. "Paul Burridge" wrote in message ...

I believe Paul is trying to determine the 'loaded" Q in order to obtain best selectivity (narrowest bandwidth). Is this true Paul? Some clarification is necessary! The application is the tank in a frequency multiplier. I am seeking to select for the 5th harmonic. Therefore, the tank needs to have as little loss as possible given the fact that the 5th will be way down dB-wise on the fundamental. I can't afford to attenuate it too much as it's already weak to begin with. Ergo, I need the lowest loss components and the best selectivity for the desired 5th harmonic. |
