The basic structure of the coaxial connector includes: the center conductor; the dielectric material outside the conductor, or the insulator; the outermost is the external contact, which acts like a coaxial cable outer shield, that is, the transmission signal , As a shield or circuit grounding element. Coaxial connectors are divided into: SMA, SMB, BNC, TNC, SMC, N type, BMA and so on.

1. Common knowledge of RF coaxial connectors

(1) Male: male joints, threads, including, which is the needle, sometimes called "J" mouth.

(2) Female: female connector, thread outside, which is a hole, sometimes called "K" mouth.

(3) RP: Reverse Polarity means that the head and the inside of the needle is the opposite.

(4) Bulkhead: is the lockable screw on the board of the connector with the Secretary, the screw and the retaining wall, generally used for the board.

(5) PCB: is a foot, you can weld the connector on the board.

(6) Panel: is a screw hole, screw can be locked on the board connector.

2. Describe the common elements of the RF connector connector

(1) Connector type: SMA, SMB, BNC, TNC, SMC, N type, BMA and so on

(2) Characteristic impedance: 50 ohm mark 50 or 50 is not marked, 75 ohm mark 75

(3) contact key way: male, female

(4) Shell form: Straight: Not marked; Curved: W

(5) Mounting Type: Flange: F Nut: Y Solder: H

(6) wiring type: adapter cable type, diameter diameter requirements

(7) attenuation: corresponding to different frequency bands of the RF signal through the resulting signal strength attenuation

(8) Thread type: external thread, internal thread

Note: Usually the equipment side of the connector are female thread, the cable side of the male thread.
