RG316 is a commonly used RF coaxial cable, known for its small diameter and lightweight construction, making it ideal for applications where space is limited. The design of RG316 provides excellent signal transmission characteristics while maintaining good flexibility and durability. With a nominal impedance of 50 ohms, RG316 is a standard choice for RF systems and is widely used in telecommunications, aerospace, defense, and other fields.
Structure of RG316 Coaxial Cable:
· Center Conductor: Typically made of a 7-strand braided silver-plated copper wire, this construction enhances the flexibility and signal transmission capability of the cable. The diameter of each strand is about 0.17mm, and the total diameter is approximately 0.54mm.
· Insulating Dielectric: Made from PTFE (polytetrafluoroethylene), which offers low loss, high insulation properties, and a wide temperature range. It ensures that the signal is not affected by external interference and can withstand temperatures from -55°C to 200°C, with a diameter of approximately 1.52mm.
· Outer Conductor (Shielding): Typically composed of silver-plated copper wire braided with 95% coverage, this shielding protects against external electromagnetic interference and prevents internal signal leakage, ensuring signal stability and integrity. The outer diameter is about 2mm.
· Jacket: Usually made from FEP (fluorinated ethylene propylene copolymer), often in brown, with excellent corrosion resistance, abrasion resistance, and anti-aging properties. It protects the internal structure of the cable from external environmental influences. The outer diameter is about 2.5mm.

When to Choose RG316 Coaxial Cable:
1.High-Frequency Signal Transmission
RG316 is ideal for applications requiring high-frequency signal transmission. For example, if you need to handle signals above several hundred MHz (such as 2.4GHz Wi-Fi, Bluetooth, LTE, etc.), RG316 is a suitable choice because it has low attenuation and can maintain good signal quality at high frequencies.
2.Limited Space or Flexible Wiring Requirements
RG316 is soft and lightweight, making it perfect for applications with limited space or complex wiring. Its high flexibility makes it ideal for environments where the cable needs to be bent or stretched, such as in small devices, electronics, drones, etc.
3.High-Temperature or Durability Requirements
RG316’s polyester insulation has excellent heat resistance, making it suitable for use in high-temperature environments (typically -40°C to +80°C). If your application involves high-temperature environments (such as automotive electronics, aerospace, etc.), RG316 is a great choice.
4.Compact Devices or Tight Installations
With a small outer diameter (approximately 3.2mm), RG316 is advantageous for devices with compact designs (such as drones, sensors, etc.). It can transmit signals in tight spaces without taking up too much room.
5.Low to Medium Power Signal Transmission
RG316 is suitable for low to medium power applications, such as certain wireless transmission devices, antenna connections, and GPS systems. It is designed for RF signal transmission, but if the power is too high, thicker cables may be preferred to reduce signal attenuation.
6.Long-Distance Applications with Low Signal Attenuation
RG316’s design makes it suitable for longer signal transmission distances, particularly in RF applications where signal clarity and quality are crucial. While it has slightly higher attenuation than thicker coaxial cables, it is still effective for most long-distance signal transmissions.
7.Wireless Communication and Data Transmission
If you're designing or maintaining wireless communication systems (such as Wi-Fi, Bluetooth, cellular communication, etc.), RG316 is ideal for connecting devices to antennas. It provides good electrical performance to ensure stable signal transmission.
8.RF Testing and Laboratory Applications
In laboratory environments where precise control of signal transmission is required, RG316 is often used to ensure stable signal transmission and high-frequency signal stability.
In conclusion, the key factors for choosing RG316 coaxial cable are whether the application involves high-frequency signal transmission, whether space is limited, whether high temperature resistance is required, and the need for flexibility. If these conditions apply, RG316 is an excellent choice.
