The cables themselves are useless unless they end with a कनेक्टर or a more special coaxial कनेक्टर. A coaxial कनेक्टर allows one cable to be connected to another cable or a device. Therefore, there are two different types of कनेक्टरs: those connected to the cable and those connected to the device. The device कनेक्टरएक चार-प्वाल flange छ।
१. केबल केन्द्रीकृतकनेक्टर
In a cable, the कनेक्टर is mechanically tightly connected to the end of the cable. Once the कनेक्टरएक केबल संग जोडिएको छ, यो एक केबल विधानसभा बन्छ। आरएफ ईन्जिनियरहरु त्यसपछि आफ्नो भाग अनुसार प्रत्येक भाग जोड्नुहोस्। जब मात्र केहि केबल असेंबलीहरु आवश्यक छ, उनीहरु अधिक सस्तो र छिटो आफैंले भेला गर्न को लागी छन्; तर जब केबल असेंबलीहरु को एक धेरै आवश्यक छ, यो केबल असेंबलीहरु किन्न को लागी राम्रो छ।
2. कनेक्टर
प्रत्येक को लक्ष्यकनेक्टर is the same, with minimum insertion loss. Although the insertion loss of the कनेक्टर is very small compared with the cable, the कनेक्टर does have an insertion loss, and there are many different types of कनेक्टरs. Almost all कनेक्टर families have कनेक्टरs suitable for cables and devices. As a general rule, the कनेक्टरs of one group will not match the कनेक्टरs of another group.Because some कनेक्टरs 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 कनेक्टरs to the small कनेक्टर family available. If the cable needs to carry high-power radio frequency signals, a large-diameter cable is required, so a large कनेक्टोr आवश्यक छ।
The second reason is evolution. As the times change, कनेक्टर 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 कनेक्टर type each time.
३. एडाप्टर
यी फरक कारणकनेक्टरपरिवारहरु, एक रोचक घटना उभिएको छ। आरएफ इन्जिनियरहरु एक संग एक केबल जडान गर्न बाध्य छन्कनेक्टर to another cable or device with a different कनेक्टर family. This cannot be done. The adapter is that they are in step. Adapters, also called coaxial adapters, are short bilateral कनेक्टरs. On one side is one type of कनेक्टर, and once is another type of कनेक्टर.
