??? How do you get to that 45 ohm figure. The input has a pair of 100R in parallel, so I can't see how it can be 45R input impedance. Did you derive that figure based on observing the amplitude change of the Tbolt when connected to the board, and when disconnected? If so I'm be more likely to suspect the the T output impedance isn't 50R.
Enquiring mind wishes to know :)
