Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would
be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate
that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views.
It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if
you would like to post something on RF Cafe's
Facebook page, please do.
Below are all of the forum threads, including all the responses to the original posts. layla Post subject: Butler Oscillator Design Posted: Wed Aug 16, 2006 3:13 pm Captain Joined: Thu Aug 10, 2006 7:09 pm Posts: 7 I need to design a 315MHz crystal oscillator. I'll go for a Butler Oscillator with a crystal running at 105MHz then use a tank circuit on the collector to get the 3rd harmonic thus achieving the needed 315MHz. My problem is that I don't know the exact math I have to use to calculate the component values of the oscillator. I know the circuit model and the only thing I found online was general tips on the design. I'd appreciate any advice on how to find out the exact values I need for this circuit.

See pages 250-279 of Design of Crystal and Other Harmonic Oscillators by Benjamin Parzen with Arthur Ballato. It was published in 1983 by Wiley-Interscience, and is available by inter-library loan if your library doesn't have it. His 29 pages on a single oscillator is pretty exhaustive and detailed. Good Luck! Fred Posted 11/12/2012 | ||||||
