What is RF tnc connector? What are the specific performance parameters required?

NC connector is a kind of radio frequency (RF) connector, its full name is "Threaded Neill-Concelman", is a kind of threaded coaxial RF connector, widely used in the field of high-frequency signal transmission. In this paper, we will introduce the basic structure of the TNC connector, performance parameters, application areas. First, the basic structure of the TNC connector is mainly composed of inner conductor, outer conductor, insulator, threaded ring and keep the ring. The inner conductor and outer conductor for the coaxial structure, the insulator is used to isolate the inner and outer conductor, threaded ring and keep the ring used to connect and fix the TNC connector and radio frequency devices. Second, the performance parameters required 1. Frequency range: TNC connector frequency range is generally between DC-11GHz, with better high-frequency performance. 2. impedance matching: TNC connector impedance is generally 50 ohms or 75 ohms, to ensure that the impedance match with the RF device. 3. insertion and extraction: TNC connector insertion and extraction is generally more than 500 times, to ensure that the connector in the long-term reliability in use. 4. Voltage and current resistance: TNC connector voltage and current resistance requirements are high to ensure the stability and reliability of the connector in high power transmission. 5. heat and cold resistance: TNC connector temperature resistance range is wide, generally can be used in -65 ℃ ~ +165 ℃ temperature range. Third, the application areas TNC connectors are widely used in telecommunications, military, aviation, space and other fields, such as satellite communications, radar, navigation, radio frequency measurement. As TNC connectors have better high frequency performance, good impedance matching performance and reliable connection performance, they are widely used in fields requiring high performance signal transmission.
