Detailed BNC RF Connector Introduction
BNC RF connector, the most widely used card connector and widely used in oscilloscope and network analyzer. The early Q9 connector in China is similar to it. Its basic features are:
Use frequency: DC to 4 GHz. However, with the progress of production technology, there are BNC RF connectors and RF adapters that can reach 8GHz. For details, please refer to the precision adapter of microwave supermarket, such as n (male) - BNC (female) precision adapter, dc-8ghz. The product interface is based on IEC 60169-8. This product first appeared during World War II. In order to realize fast and reliable signal interconnection, it is designed as bayonet type. However, due to its bayonet connection, the shielding performance of signal transmission is not good, and the impedance matching degree is not high, so the frequency range that the product can support is not high. Signal instability also occurs during vibration. Therefore, with the development of 5g, the application scope of this product will be smaller and smaller.
Generally, there are 75 ohm and 50 ohm BNC RF connectors on the market. Moreover, if the application frequency is very low, the two can also be used together. This is rarely seen in the industry.
Features: snap pin locking device, fast connection, small protection and wide use
Applications: data transmission system, telecommunication system, network system, instrumentation
BNC head can be installed by screwing and crimping.
The biggest feature of BNC is that the female head has two ears and the foreman has two slots. Can connect quickly. But the protection is poor. BNC RF connectors are now very common.
BNC head has straight head and elbow, and the cable diameter that can be connected ranges from 1.8 to 10.8mm. In addition, there are waterproof ones used on circuit boards.
