BNC Interface

1. What is BNC Interface?

The BNC (Bayonet Neill-Concelman) is a snap-on RF coaxial connector with a 75Ω impedance design and an operating frequency range of 0-4GHz. It is suitable for video signals, RF transmission, and instrumentation connections.

 

2. What is the Core Structure of BNC Interface?

Connector Type: Male (plug) and Female (receptacle)

Contact Elements: Center Conductor (Brass/Beryllium Copper with Gold Plating) + Insulation (PTFE)

Locking Mechanism: Quick-release snap-on connection (90° rotation for securement)

 

3. What are the Performance Parameters of BNC Interface?

Voltage Standing Wave Ratio (VSWR): ≤1.3 @ 1 GHz

Insertion Loss: ≤0.2 dB @ 1 GHz

Durability: 500 plug-in/plug-out cycles

 

4. What are the Typical Applications of BNC Interface?

Security and Surveillance: Analog Camera Video Transmission

Broadcasting Equipment: SDI Signal Interface

Test Instruments: Spectrum Analyzer Probe Connection

 

5. Technology Evolution of BNC Interface

The next-generation BNC-LD (low-loss type) increases the upper frequency limit to 6 GHz and utilizes silver-plated contacts to reduce resistance, meeting the testing requirements of 5G base stations.
