N-Type Plug for RF and Microwave Assemblies
It terminates RG-58C, 141A, or Belden 9907 cable via a solder contact and a clamp-style shield termination — the clamp grips the braid, the centre conductor solders into the pin. The silver-plated brass body and centre contact keep surface resistance low at RF; the PTFE dielectric holds the impedance steady across the band. Threaded coupling secures the mate, and the free-hanging body suits in-line cable runs where a panel jack is not available.
Cable Match and Termination
This plug is specced for RG-58C, 141A, and Belden 9907 — three common 50 Ohm cables with similar dielectric diameters. The solder contact and clamp shield mean you prep the cable: strip the jacket, trim the braid, tin the centre conductor, solder the pin, then slide the clamp over the braid and tighten. No crimp die needed; the clamp takes the strain. Match the body to the reel — if your cable is not one of the three listed, the dielectric OD may not seat correctly in the clamp, and the impedance match drifts.
Frequency and Voltage Headroom
Rated to 11 GHz, this plug covers L, S, C, and most of X band — enough for test equipment, antennas, and microwave links that stay below 11 GHz. The 1000 V rating is peak; at RF the limiting factor is usually the power-handling of the cable, not the connector. The 500-cycle mating life is field-service grade — you can swap it on a test cable or antenna feed several times per week for years before the silver plating wears through.
