Hello all,
How does transformer coupling work? It seems simple enough to swap a coupling cap with a 1:1 coupling transformer but what about step up transformers? Suppose you use a 5k:10k coupling transformer, does the second stage see a source impedance of 10k? If so it seems like transformer coupling is a nice way to match input and output impedances as well as improve hi frequency response.
Also suppose my power stage requires a 20Vpk-pk input then if I use this 5k:10k transformer can I simply have my driver stage output 10Vpk-pk since the voltage at the secondry will be 20Vpk-pk? Any help or references to transformer coupling online would be helpful.
Also, where can I buy Tamura transformers and chokes in the US?
Thanks for all the help guys.
