Is RF output waveform inverted to RF input?
Why asking this question is that:
High speed TX unit and RX unit is developed separately where high speed data is amplified by HMC659. HMC659 is located at boundary of TX and RX unit on TX side. So logic of the data is inverted or non-inverted needs to be clarified.
I guess it is inverted but diagrams in datasheet do not contain the level of detail to judge whether inverted or non-inverted.
