!

if i built a 5 port device, what would be the insertion loss (so i can
calculate the power rating of the resistors)? would it be 3dB or 7dB (the
signals aren't in phase or anything, in fact they're different frequencies).

My guess would be 7 dB. But multi-way Wilkinsons are too bizarre for
my brain ! I would do what Roy says and model it with SPICE or
whatever.

I did model a normal 2-way Wilkinson combiner with only a single input
(the microwave kind with actual transmission lines) and to my surprise
(and probably Roy's) it was perfectly matched at one frequency, had
perfect isolation at one frequency and gave a 3 dB loss from one of
the two input ports to the common port (all at the design frequency
only, of course).
