What types of RF connectors are there?

　　There are currently many types of RF connectors on the market, each with its own impedance and shape. This section will discuss the different types of RF connectors.

　　1. Classification by Connection Method:

　　Bayonet Type (Internal Bayonet, External Bayonet): BNC Thread Type (Right-hand Thread, Left-hand Thread, External Thread, Internal Thread) (M): L29-7/16, N, F, TNC, SMA, SMC, SSMA, SSMB, FME, L9 (1.6/5.6), 7mm, 3.5mm, 2.4mm, K (2.92mm), 1.85mm, 1mm;

　　Push-in Type (Direct Insertion, Self-locking): SMB, SSMB, MCX, MMCX, SMP, SMI, BMA, SAA;

　　Flange Connection Type (F): Most of the above can be manufactured in flange form.

　　Soldered Type: Most of the above can be manufactured in solder form. (Manufacturing depends on demand)

　　Board-to-Board Connection: Used to connect two PCB boards.

　　Basic Knowledge: For wireless RF testing applications, device-side connectors are usually female with external threads, while cable-side connectors are mostly male with internal threads.

　　2. Classification by Connector Size:

　　Standard Type: UHF, N, 7/16, 7mm;

　　Miniature: BNC, TNC;

　　Ultra-miniature: SMA, SMB, SMC, MCX, BMA, SAA, 3.5mm;

　　Micro: SSMA, SSMB, MMCX, 2.4mm, K (2.92mm), 1.85mm, 1mm;

　　3. Classification by Connector Characteristic Impedance:

　　50Ω

　　75Ω

　　4. Classification by Connector Bending Angle:

　　Straight Connector: A common type of connector is the straight connector.

　　Elbow Connector: The connector is at an angle to the mounting cable。
