What the 12.4 GHz Ceiling Means for Signal Path
The 5447647-2: The 12.4 GHz max frequency covers the full L, S, and C bands plus most of the X band — enough for radar, satellite downlinks, and test instrumentation up to Ku-band entry. The PTFE dielectric holds the impedance steady through the crimp transition, so the VSWR stays low across the band. For runs above 12.4 GHz, you'd step to an SMA 2.92 or 2.4 mm interface; for everything below, this plug keeps the signal clean.
Crimp Termination and Field Assembly
Crimp on both the centre pin and the shield braid — no solder, no heat gun. The threaded coupling nut gives a positive mechanical lock that holds under vibration, and the nickel-plated brass body resists corrosion in outdoor or lab environments. The kit includes the ferrule, so you're not hunting for a separate crimp ring. 500 mating cycles means it can handle repeated connect/disconnect in test setups or field-service kits without the plating wearing through.
