RF Performance and Temperature Range
The 1408149-2: Rated for 50 Ohms impedance and a maximum frequency of 6 GHz, this plug handles the common sub-6 GHz bands for Wi-Fi, cellular, and IoT applications. The 500 mating cycles mean it can survive repeated connect-disconnect cycles in test or field-service scenarios without the contact fretting.
Termination and Cable Compatibility
The centre contact is soldered, while the shield is crimped using the supplied ferrule. The kit is specified for RG-316 cable — a common 50 Ohm coax with a solid or stranded centre conductor. If you are working with RG-174, the cable diameter is close but the dielectric and braid density differ; the crimp ferrule and centre contact dimensions are tuned for RG-316, so stick with the listed cable group for a reliable termination.
