50 Ohm BNC HD Receptacle for 6 GHz Signal Paths
The 034-5022: It carries a 6 GHz frequency maximum, which puts it above the standard 4 GHz BNC ceiling — the HD (high-density) variant extends the usable bandwidth for applications like base station backhaul, test equipment, or instrumentation where the signal integrity needs to hold up past the usual BNC roll-off.
The 6 GHz frequency rating is the practical limit where the connector maintains a 50 Ohm impedance match — above that, the return loss climbs and the signal degrades. For a 4 GHz BNC, this part gives you headroom; for a 6 GHz design, it is the ceiling. The 500-cycle mating life is standard for a bayonet-lock RF connector that sees periodic disconnect during calibration or reconfiguration. The gold plating on the beryllium copper center contact handles that cycle count without the oxide buildup that would raise contact resistance on a tin-plated part.
Through-Hole Mounting and Solder Termination
The shield termination is solder, not a crimp ferrule, which means the ground connection is made at the board level, not to a cable braid. The nickel-plated brass body gives a silver appearance and provides the corrosion resistance expected in indoor equipment or rack-mount gear. The single-port configuration is the standard for a discrete PCB-mounted BNC jack.
