What is RF coaxial connectors?

2023 06/06

RF coaxial connectors:

A coaxial connector refers to a part used to connect the ends of two shafts, ensuring that the centerlines of the two shafts are on the same axis; the usually shielded wire is made in the mode of coaxial wire. Shielded coaxial wire can be used to transmit RF signals.

(1) SMA: Small A type; thread locking type; two forms: external thread + hole/internal thread + pin; or RP-SMA external thread + pin/internal thread + hole in reverse. The common impedance is 50Ω; the frequency is 0-18GHz.

(2) SMB: Small B type, the common impedance is 75Ω; different in appearance and hole diameter; it is of the push-in locking type

(3) SMC: Small C type, thread locking type, different in appearance and hole diameter;

(4) BNC: Bayonet nut connector; it is of the bayonet type, it can be connected and detached quickly, and the frequency is 0-4Ghz

(5) TNC: A variant of BNC, which adopts threaded connection, and the frequency range is 0-11Ghz

(6) N-type: Invented by Neill, thread locking type, the appearance is 20-25mm, the frequency range is 0-11Ghz and the precision up to 18GHz

(7) DIN type: DIN standard connector, also known as 7/16 or L29, large threaded connection, the appearance is 30-35mm, usually it is water-proof, and the frequency range is 0-11Ghz

(8) MCX: Miniature coaxial, push-in connection, with a height of 8.63mm; it is divided into straight type and right-angle type

(9) MMCX: Micro-miniature coaxial, push-in connection, with a height of 7mm, 30% smaller than MCX;

(10) F-Type: Thread locking, convenient insertion, 75Ω, usually used for TV antenna, the maximum frequency is 2.4Ghz

(11) Micro coaxial: Ultra-miniature wire-to-board connector
