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-छिद्र फ्लॅंज आहे.
1. केबल केंद्रीकृतकनेक्टर
In a cable, the कनेक्टर is mechanically tightly connected to the end of the cable. Once the कनेक्टरकेबलशी जोडलेले आहे, ते केबल असेंब्ली बनते. आरएफ अभियंते नंतर प्रत्येक भाग त्यांच्या स्वतःच्या गरजेनुसार जोडतात. जेव्हा फक्त काही केबल असेंब्लीची आवश्यकता असते, तेव्हा ते अधिक स्वस्त आणि वेगवान असतात ज्यांना स्वतः एकत्र करणे; परंतु जेव्हा बर्याच केबल असेंब्लीची आवश्यकता असते, तेव्हा केबल असेंब्ली खरेदी करणे चांगले.
2. कनेक्टर
प्रत्येकाचे ध्येयकनेक्टर 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 कनेक्टआर आवश्यक आहे.
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.
3. अडॅप्टर
या भिन्न कारणांमुळेकनेक्टरकुटुंब, एक मनोरंजक घटना उदयास आली आहे. आरएफ अभियंत्यांना केबल एकाशी जोडण्याची सक्ती आहेकनेक्टर 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.
