transmission line transformer
Hello,
I reviewed the Polyfet application note and am somewhat confused.
They are using a transmission line (equivalent to PSpice T model) and two inductors, one parallel to the outer conductor and one to the inner. My intuitive understanding is, that only one inductor should be used, parallel to outer conductor. But I'm not sure about. I think however, that the Polyfet equivalent circuit would show incorrect behaviour when operating the line in regular single ended mode, while a single inductor would be ignored then, as necessary.
Regards,
Frank
