First, RF connector introduction
The RF connector is
connected to a coaxial cable, microstrip line or other RF transmission
line to enable the electrical connection of the transmission line,
separation or the transfer of different types of transmission line. It
belongs to mechatronics products and acts as a bridge.
The model
of the RF LRM200 RF Coaxial cables, LMR400 RF Coaxial Cable or RG58 RF Coaxial Cables connector consists of two parts: the main code and the
structure code, separated by a dash "-". The main code name of the main
code name RF connector adopts the internationally-used main code name,
and the naming of different structural forms of specific products is
specified by detailed specifications. The structure of the structure
code RF connector.
Second, the classification of RF connectors
1) According to the connection interface structure is divided into:
Bayonet type (internal bayonet, outer bayonet): BNC
Threaded
(right-handed, left-handed): 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 (in-line, self-locking): SMB, SSMB, MCX, MMCX, SMP, SMI, BMA, SAA;
Flange connection:
2) Classified by size:
Standard type: UHF, N, 7/16, 7mm;
Small: BNC, TNC;
Ultra-small: SMA, SMB, SMC, MCX, BMA, SAA, 3.5mm;
Micro: SSMA, SSMB, MMCX, 2.4mm, K (2.92mm), 1.85mm, 1mm;
Third, the main specifications of the RF connector
Impedance:
Almost all RF connectors and cables are standardized to an impedance of
50 Ω. The only exc
