What connector does a 50 ohm impedance coaxial cable match with?

50 ohm coaxial cable such as RG58, RG174, RG 316, 5D-FB matching typically uses SMA or BNC interfaces. ‌

In RF circuits, impedance matching of 50 ohms is a common standard because the impedance of most RF devices and equipment's input or output ports is basically 50 ohms. This design ensures the efficiency and stability of signal transmission.

For example, the through type 50 Ω load resistor/50 Ω impedance adapter uses a standard BNC interface, which can match any oscilloscope to ensure signal integrity and consistency. In addition, products such as current probes, current systems, Roche coils, and differential probes often use BNC interfaces to ensure the quality and efficiency of signal transmission.

Impedance matching is a key factor in ensuring optimal performance when interconnecting electronic devices. In the field of radio frequency, the use of 50 ohm impedance matching wires is very common, especially in applications that require the transmission of high-frequency microwave signals. By using the BNC interface, signals can be effectively transmitted from the signal source to the load while avoiding signal reflection, thereby improving energy efficiency.

In summary, 50 ohm impedance matching mainly uses BNC interfaces, which have been widely used in RF circuits due to their efficient and stable signal transmission characteristics.
