Product type
Coaxial RF cables are specialized cables designed to carry radio frequency signals with minimal loss and interference. They consist of a central conductor, an insulating layer, a metallic shield, and an outer insulating layer, which work together to protect the signal from external electromagnetic interference. These cables are commonly used in various electronic applications, including telecommunications, broadcasting, and data transmission.
| Conductor material | Copper or aluminum |
| Impedance | 50 ohms or 75 ohms |
| Outer diameter | 3.7 mm to 10 mm |
| Temperature range | -40°C to +85°C |
| Shielding type | Foil or braided |
| Maximum frequency | Up to 18 GHz |
When selecting coaxial RF cables, consider the specific application requirements such as impedance, frequency range, and environmental conditions. It's important to specify the length, conductor material, and shielding type when requesting a quote. Additionally, inquire about any necessary certifications or standards that may apply to your industry.
