KN5L Two Winding 1:1 Transformer Balun


FT82-61 Ferrite Core
Ten turn twisted pair
1:1 Turn ratio
#22 Wire
Balun loss remained unchanged from 10 to 100 watts

SimSmith Model


Both coupling coefficient, k=0.9924, and leakage inductance, L2=.0524 uH, are evaluated.
Both matched loss, using xMtch, and unmatched loss, using useZo, are evaluated.
