Thanks, I no longer have academic access, so will need to buy or get site of the paper some other way. However, there might be alternatives/better solutions to pursue.
I found ¡°Analysis and Performance of Antenna Baluns¡± by Lotter Kock
Victor Reijs might be interested in this. This models a balun as a delta-connected network of impedances, provides a good explanation of how the common mode current occurs (another question I think Victor has) as well as giving several means of testing, including back-back and the ¡°Woodward¡± method, tabulating their usefulness.

The 622-kk81 is a non catalog part. I'd find something that's in stock. If you need 3 isolated windings, I'm sure they've got something.¡±
It appears ordering direct from Mini-Circuits requires a minimum order value of $50. With shipping costs and import duties, the cost of 622-kk81 would be high, so thanks Jim for alternative part you use.
Neither part is available from Digikey or Mouser, so a look though what they have in stock to see if there is yet another alternative might be more fruitful and cost effective.
Kind regards
