[Amps] Hf Combiners and SPlitters

I am trying to find formulas for a Hybrid style combiner that seems to be a 
4 port Tee style splitter/combiner.

It would resemble most formulas I have found for a LC Wilkinson style 
combiner except that the only formulas I have seen employ Pi-networks.

The splitter uses 2-1"X1" mix 43 broadband transformers and the combiner 
consist of 2-1-1/4"braodband transformer.

It is similar in design to that of Helge Granberb's design but instead of 
using a 4:1 step-up and down transformer you are using a Tee network to 
simulate 100 ohms.  I figure the calculations for the inductor should be the 
same as in the Pi network but cant find anything online to confirm this and 
have not seen any formulas for the capacitance for a tee network.

Any help will be appriciated.
