Realistically, I doubt that you will get the relevant information from
the manufacturer(s) in order to compare.
Some parameters which affect RF performance:-
Dielectric constant and losses of material between conductors
Spacing of conductors (variable through connector)
Diameter or other geometry of individual conductors (variable through
connector)
Material of connector conductors
Contact resistance
Proximity and effectiveness of shielding
Impedance matching to input and output
Good luck & feedback would be nice!

Hi All SI Experts,
One question.
If I want to use one connector to replace another connector because of cost issue, what criteria are needed to prove they are electrically equivalent.
Especially the substitution is happened for high speed / low swing signals, such as RAMBUS signals, which have 200ps for rising time.
Any comments or suggestions are appreciated.
Thank you for helps in advance.
