The cables themselves are useless unless they end with a stik or a more special coaxial stik. A coaxial stik allows one cable to be connected to another cable or a device. Therefore, there are two different types of stiks: those connected to the cable and those connected to the device. The device stikhar en fire-hullers flange.
1. Kabel centraliseretstik
In a cable, the stik is mechanically tightly connected to the end of the cable. Once the stiker forbundet til et kabel, bliver det til en kabelsamling. RF -ingeniører forbinder derefter hver del efter deres egne behov. Når der kun er brug for få kabelsamlinger, er de mere overkommelige og hurtigere at samle alene; men når der er brug for mange kabelsamlinger, er det bedre at købe kabelsamlinger.
2. Stik
Målet med hverstik is the same, with minimum insertion loss. Although the insertion loss of the stik is very small compared with the cable, the stik does have an insertion loss, and there are many different types of stiks. Almost all stik families have stiks suitable for cables and devices. As a general rule, the stiks of one group will not match the stiks of another group.Because some stiks are large in physical size, while others are small. If an inexpensive cable assembly is needed, then choose a small diameter cable, which limits the choice of stiks to the small stik family available. If the cable needs to carry high-power radio frequency signals, a large-diameter cable is required, so a large connector er påkrævet.
The second reason is evolution. As the times change, stik manufacturers often improve the connection according to actual needs, or reduce the insertion loss, or facilitate the use of the connection. Significant changes are made to an existing stik type each time.
3. Adapter
På grund af disse forskelligestikfamilier, er der opstået et interessant fænomen. RF -ingeniører er tvunget til at forbinde et kabel med et kabelstik to another cable or device with a different stik family. This cannot be done. The adapter is that they are in step. Adapters, also called coaxial adapters, are short bilateral stiks. On one side is one type of stik, and once is another type of stik.
