How can you make a combination of transmission lines that are 
parallel at one end and in series at the other that come out to 
2.25:1 ratio?

Whatever transformer is used, it has to be an autotransformer or 
split winding design.

Trifilar would make mutual coupling very high, and work with a 2/3
winding tap for a 2.25 ratio. Coax would only increase loss and 
decrease BW in this system compared to a trifilar autotransformer.
