Those are Indium Phosphide Gunn Oscillators which are highly nonlinear 
and have significant dynamic component to their Z.
So you can't expect all the usual combining rules (which are typically 
based on constant impedances, etc.)

This might be one of those "optimize the dynamic match to suck more 
power out of the device" kind of things.
