The 1-1337445-0: The PTFE dielectric holds the impedance line at 50 Ohms across the full rated frequency range.
The 4 GHz upper frequency limit covers the L, S, and lower C bands.
The shield termination is a solder cup or turret (the spec lists shield termination as solder), so you will hand-solder the braid and the centre conductor. The through-hole mounting gives a stronger mechanical anchor than a surface-mount BNC, which matters when the cable is repeatedly flexed at the connector.
