Product Overview
The model of SMA Male for RG58 RG14 is SMA-C-J3.SMA connectors are commonly used to provide RF connections between circuit boards and many microwave components, including filters, attenuators, mixers, and oscillators. The connectors feature a threaded external connection interface with a hexagonal shape that allows for wrench-tightening. They can be tightened to the correct seal using a special torque wrench, allowing for a good connection without overtightening.
The first SMA connectors were designed for use with 141 semi-rigid coaxial cable. The original SMA connectors can be called minimal connectors because the center of the coaxial cable forms the center pin of the connection, eliminating the need for a transition between the coaxial center conductor and the special connector center pin.


Advantages and Disadvantages
The advantage is that the cable dielectric connects directly to the interface without an air gap. The disadvantage is that only a limited number of connect/disconnect cycles are possible. However, this is less likely to be a problem for applications using semi-rigid coaxial cable, as the installation is typically fixed after initial assembly.
