The TNC (Threaded Neill-Concelman) connector is a threaded version of the BNC connector. The connector has a 50 Ω impedance and operates best in the 0–11 GHz frequency spectrum. It has better performance than the BNC connector at microwave frequencies.
Invented in the late 1950s, the TNC connector has been employed in a wide range of radio and wired applications.

SMA (SubMiniature version A) connectors are coaxial RF connectors developed in the 1960s as a minimal connector interface for coaxial cable with a screw type coupling mechanism. The connector has a 50 Ω impedance. It offers excellent electrical performance from DC to 18 GHz.
Designed in accordance with MIL-C-39012 specifications, SMA lineup has one of the most extensive variety of applications including Semi-Flexible/Flexible cable, Receptacle, PCB, and Reverse Polarity option.

Developed in the 1980s, MCX connectors are coaxial RF connectors that have the same inner contact and insulator dimensions as the SMB connector but are 30% smaller. They use a snap-on interface and usually have a 50 Ω impedance. They offer broadband capability from DC to 6 GHz.
While maintaining high performance, the reduced connector size benefits any applications where the space reduction matters such as GPS, Wireless communication, PCB layouts.
