John,

This is far enough away from the original design frequency that it's anybody's 
guess.  It's really a function of the design of the transition.  It's a lot 
harder to make a transition work well over a broad bandwidth.  My guess is that 
it probably works OK for our purposes at 24 Ghz (it transfers energy without 
too much loss) but the that the impedance match isn't all that great.  It's 
anybody's guess how well it works at 24 GHz unless it can be measured.
