I have two questions relating to the return loss of the ADMV1014:
1. The datasheet says the inputs and outputs are matched 50 ohm (or 100 ohm diff) - these look to be buffered based on the block diagram. Am I right that it is okay to put matching networks on these?
2. The return loss measurements were measured at an ambient temperature of 25 degC. Do you know how these might be expected to change (if at all) over temperature?
