The snap-on fastening gives a quick mate without the torque tooling a threaded SMA requires, though the 100 mating cycles mean it is not a daily-disconnect port. The gold-plated brass body and gold centre contact resist corrosion in the RF path, and the PTFE dielectric holds the impedance steady across the -40°C to 80°C operating range. ## Cable Assembly Fit This plug comes as two pieces — the connector body and one contact — both requiring solder termination for the shield and centre pin. It is built for RG-402 (.141\" semi-rigid) cable; the cable group is specified, so the centre conductor and dielectric diameters are a known fit. For a build-to-print cable assembly, the BOM needs the 1408346-1 plus the specified RG-402 cable; no separate backshell or ferrule is included in this kit. ## Obsolete — Sourcing Path No direct cross-reference or pin-compatible alternative is on record from the manufacturer.","metaTitle":"TE Connectivity 1408346-1 QMA Plug, 50 Ohm, 6 GHz, RG-402","metaDescription":"TE 1408346-1 QMA plug, male pin, 50 Ohm, 6 GHz max, 0.25 dB insertion loss, snap-on, RG-402 semi-rigid cable.
