The RF Workbench / Transmission Line Transformers
« on: January 16, 2023, 2007 UTC »
I mentioned over here that I was trying to find more information on designing transmission line transformers: https://www.hfunderground.com/board/index.php/topic,89881.msg335362.html#msg335362
I got what I was looking for and I figured that I would share:
The first reference is the second edition of a book that I own in print (first edition). Bowick, C., "RF Circuit Design". This section is basically untouched from the first edition: https://ia802603.us.archive.org/7/items/RFCircuitDesign2ndEdition/RF%20Circuit%20Design%20-%202nd%20Edition.pdf Starting on page 181 ("Broadband Transformers"), and especially pages 182-183, "Practical Winding Hints".
Also, Badger, G., “A new class of coaxial line transformers,” Ham Radio Mag azine, Part 1, 12–18, Feb. 1980, and Part 2, 18–29, Mar. 1980.
