The 903-406J-51R: It terminates via a solder cup — you tin the centre conductor and the shield braid, then solder each into its cup. The PTFE dielectric and gold-over-brass body keep the signal path stable from DC through 4 GHz, covering ISM bands, cellular, and GPS /L2 without a second thought.
The 4 GHz maximum frequency is the usable top end before insertion loss climbs past 0.3 dB. The 500 mating cycles come from the gold-on-gold contact interface.
50 Ohm nominal, standard for SMB interfaces and common RF systems.
Rated for 500 mating cycles, supported by gold-on-gold contact plating.
