Product details

20 GHz SMA Plug for Cable Assemblies

The shield termination is crimp, and the contact termination is solder — a standard combination that gives a reliable electrical bond at the pin and mechanical grip at the braid. This plug is specified for cable group RTK 044. That designation tells you which coax cable diameter and dielectric type the crimp ferrule and center contact are sized for. Using a different cable group risks an impedance mismatch at the connector-to-cable interface and a loose or over-crimped shield termination.

This SMA plug mates with any standard SMA female jack (receptacle) that has a threaded coupling nut — the fastening type is threaded, per the SMA interface standard. The free-hanging, right-angle body means it terminates a cable and mates to a panel- or PCB-mounted jack. The 500 mating cycle rating means the gold-on-brass contact interface will hold its contact resistance and VSWR through repeated connect-disconnect cycles in test or field-service applications.

Frequently asked questions

What cable does the 901-10851 work with?

The 901-10851 is specified for cable group RTK 044. That cable group designation defines the coax cable diameter and dielectric type the connector is sized to terminate. Using a cable outside this group will not produce a proper impedance match or a secure crimp.

Is the 901-10851 compatible with RG58 cable?

The 901-10851 is specified for cable group RTK 044, not for RG58. Cable group RTK 044 has its own specific diameter and dielectric properties; RG58 is a different cable group. Using the wrong cable group risks an impedance mismatch and a poor mechanical termination.
