The 930-187P-51T: The free-hanging, cap-style body terminates a cable end; it is not a panel-mount or PCB-launch variant.
Machined brass body with a nickel finish gives the shell good corrosion resistance and a consistent surface for grounding through the mating interface. The dielectric is PTFE, which holds a stable dielectric constant through the 6 GHz band and handles soldering temperatures during cable termination.
Yes, this is a standard QMA plug and mates with any QMA jack (receptacle) that follows the same interface definition — no keying or polarity variants to watch for. It is not compatible with SMA or BNC connectors without an adapter.
50 Ohm characteristic impedance, rated to 6 GHz maximum frequency. The PTFE dielectric and gold-plated centre contact support that band with stable RF performance.
