Cabled Connectors - Johnson offers a complete line of cabled SMA connectors for all popular cable types, including semi-rigid.

PCB Mount - Through-hole and surface-mount SMA jacks and plugs for demanding board-mount applications. Available as jacks or plugs, straight and right angle.

End Launch - The SMA end launch connector is attached to the circuit board by inserting the board edge between the legs and soldering the legs and center conductor to pads on the board. For optimum high-frequency performance, the connector to circuit board transition must be adjusted for low VSWR.

High-Frequency End Launch - High-frequency end launch connectors are used to transition microwave energy from coaxial to planar transmission line structures. These connectors provide a unique solution for microwave engineers who fabricate circuit designs on very thin high-frequency board substrates.

Self-Fixture End Launch - An ideal solution for design engineers who are obligated to cut manufacturing costs and complexity out of their circuit board systems.

Reverse polarity - Reverse polarity SMA (RP-SMA) is a variation of the SMA connector that reverses the gender of the interface. They are commonly used in Wi-Fi applications.

Quick connect - Quickly mates to a standard threaded SMA jack receptacle allowing rapid test connections to devices utilizing SMA threaded jacks. The SMA quick connect plug is recommended for test and measurement applications.

SMK 2.92 - The SMK (2.92 mm) connectors provide an excellent solution for demanding applications requiring high-frequency transmission. Although, similar to the SMA interface, a smaller internal body diameter (2.92 mm) and air dielectric provide a higher cutoff frequency and other key advantages.
