Hello,
Winding a transformer with a transmission line is a technique often used to improve the bandwidth of a transformer. The transmission line is said to "absorb" the parasitics of the transformer. This part I nearly understand. Some explanation might still be helpful.
However, I'm wondering how winding a transformer with a coaxial cable might improve the bandwidth of a transformer. I know a coaxial cable is a transmission line, but because of the shielding I thought no EM-field (or only very little) could leak out to absorb those parasitics ...
Can someone explain this to me please?
Thanks.
Charles
