SMA Plug, 50 Ohm, 12.4 GHz — Obsolete, Sourced to Order
The 447647-2: The threaded fastening (SMA standard) provides a secure, vibration-resistant mate.
Lifecycle — Obsolete, No Official Successor
No direct replacement order code is listed.
This plug is compatible with RG-142, 142A, 142B, and 400 cables — common semi-rigid and double-shielded coax types used in test equipment, telecom, and military RF assemblies. The contact and shield are both crimp-terminated, which gives a repeatable, tool-controlled termination without solder. The nickel-plated brass body and silver housing colour are standard for SMA connectors in indoor and sheltered environments.
Mating Cycles and RF Performance
The 0.3 dB insertion loss at 12.4 GHz is within the expected range for a crimp-style SMA plug; the loss contribution is dominated by the cable-to-connector transition, not the interface itself.
