R-F Cable

Cables that transmit electromagnetic energy in the radio frequency range.

Radio frequency cable is a cable used to transmit high frequency signals. It usually consists of an inner conductor (such as copper wire), insulation, shielding and outer sheath. Radio frequency cables are mainly used to connect radio frequency equipment, such as wireless communication systems, radio and television equipment, satellite communication equipment, etc. Due to the high frequency and sensitivity of RF signals, RF cables need to have low loss, low noise, high transmission efficiency and good shielding performance. Common RF cable types include coaxial cables, such as RG-58, RG-6, RG-8, etc. Different RF applications require the selection of appropriate RF cables to meet signal transmission requirements.

The characteristics of RF cables include electrical and mechanical properties. Electrical properties include characteristic impedance, transmission loss and frequency characteristics, temperature characteristics, shielding characteristics, rated power, maximum withstand voltage. Mechanical properties include minimum bending radius and weight per unit length. , maximum pull force allowed, and aging characteristics and consistency of the cable.

Product features

1. Can transmit a wider frequency band

2. High degree of defense against external interference

3. Small antenna effect and small radiation loss

4. The structure is simple, the installation is convenient, and it is relatively economical.

Product advantages

1. Shielding performance: RF cables usually adopt shielded structures to prevent interference from external interference signals.

2. Low loss: RF cables are required to have low signal loss at high frequencies to maintain the quality of signal transmission.

3. Impedance matching: The impedance matching of RF cables is an important parameter to ensure normal signal transmission. Common RF cable impedances include 50 ohms and 75 ohms. The specific impedance value should be determined according to the application requirements.

4. Sufficient bandwidth: RF cables need to have sufficient bandwidth to transmit high-frequency signals.
