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
