I'm surprised you're not using SMA edge connectors designed for 15G. The ones you're using, with the long center pin, aren't really 50 ohm above 6G. Higher freq SMAs have really tiny center pin for SMT soldering with low capacitance.

Makes sense

I work in retail but most 5G devices have these awful TS9 or similar connectors which we have to adapt to something usable like SMA

I literally have customers returning products as faulty because “the connector just will not sit correctly!” - even though it’s performing as intended
