What are good PI matching starting values for SR42W009 antenna?
I read SR42W009 datasheet but i can't find them. I also saw that there is a SR42W009 EVB but i can't find the evaluation board datasheet with the components used. I need some PI matching starting values, that can be optimized after the design of the board.

A series 1.8nH inductor followed by a shunt 1.8pF capacitor to ground between your radio and the series component would be a good start.
