What is a cable assembly?
Cable assembly are one of the very common components in the design and construction of RF and microwave systems. It is popular used to connect various of parts of an equipment. The cables are always used to route signals between the different circuit boards and modules in the projects boxes ,which also requires it to connect with antenna system. Besides , the test equipment used also need RF cables to send and receive test signals when designing, manufacturing, installing and debugging the system. It follows that the good and suitable cable assembly is really important !
The basic cable assembly consists of Coaxial Cable and Coaxial connectors.
Coaxial Cable : It is typically comprised of a center conductor, an insulating dielectric material and an outer conductor (shielding). The different coaxial cable have their different several performance parameters described in their datasheets, which change with frequency .It includes attenuation and power handling specifications. Typically, the higher frequency signals suffer from greater resistive losses, hence greater attenuation. Moreover, at certain high enough frequency, a coaxial cable begins to act as a waveguide, and a very poor TEM mode transmission line. This is known as the cut-off frequency, and should be well above the highest frequency of any desired transmission signals. 50ohm and 75ohm are most widely used .The common Coaxial cable include Semi-Rigid Cable, Semi-Flexible Cable (RG405,RG402)，Military standard RG series (RG6, RG11, RF58, RG59, RG142, RG174, RG178, RG179,RG179D, RG213, RG214, RG223, RG316, RG316D), Corrugated Coaxial Cable (Corrugated copper 1/2" cable, Corrugated copper 7/8" cable) , KSR Low Loss Cable (KSR100，KSR195,KSR200,KSR240,KSR400 ), Micro Coaxial Cable (Mic coax cable OD1.13mm,Mic coax cable OD1.32mm,Mic coax cable OD1.37mm).
Coaxial Connector : It is the components that is made at both end of a coaxial cable assembly. The type of coaxial connector is determined by matching equipment, systems, or other interconnections .Many common types of coaxial connectors can be chosen for your project ,such as: Fakra, SMA, SMB, N -type ,BNC ,TNC, MMCX, MCX,UHF ,7/16 DIN connector ,FME ,F-type, SMC, Mini-UHF, SSMB ,MC-card ,BMA, QMA, CRC9,TS9, MS-162,MS-147,RCA,GT5-1S,MCC, 1.0/2.3 connector,1.5/5.6 connector ,SMP ,SSMA connector etc. Please kindly choose the right coax connector more carefully before requiring the RF cable assembly. If you feel a little difficult to identify them, welcome to see the connectors’ pictures of RF connector catalogue.
The quality of Coaxial Cable and Coaxial connectors is really very of importance. Superbat use the good material to make the cables. The connectors used are good-Brass + 100% Teflon materials . Our coaxial cable assemblies is made by some highly trained service technician during the each hand-made procedure and then quality check of continuity and performance before shipping.
