50 Ohm Braiding Cable: Structural Features, Application Fields and Selection Guide

In the fields of modern communications, electronics and industrial equipment, various types of RF cables are widely used for the transmission of high-frequency signals. Among them, 50 Ohm Braiding Cable has become an important choice in high-frequency application scenarios due to its excellent electrical performance and anti-interference ability.
Basic Structure of 50 Ohm Braiding Cable
50 Ohm braided cable is mainly composed of the following parts:
Inner conductor
High-purity copper or silver-plated copper conductor is usually used to ensure good conductivity and high-frequency transmission characteristics.

Insulation layer
Low-loss polyethylene (PE), foamed polyethylene or polytetrafluoroethylene (PTFE) and other materials are mostly used to ensure low attenuation and high stability during high-frequency signal transmission.

Braided shielding layer
The biggest feature of 50 Ohm Braiding Cable is that the outer layer uses copper wire or silver-plated copper wire for high-density braiding shielding, which effectively prevents external electromagnetic interference (EMI) and prevents interference of its own radiation to other devices.

Outer sheath
PVC, PE or FEP materials are used as the outer sheath to enhance the cable's wear resistance, corrosion resistance and weather resistance, making it suitable for various complex environments.

Performance characteristics and advantages
Precise characteristic impedance
The 50 ohm braided cable strictly controls the characteristic impedance within the range of 50±2 ohms to ensure low reflection, low standing wave ratio and good signal integrity during high-frequency signal transmission.

Excellent anti-interference ability
The high-density braided shielding layer effectively suppresses external electromagnetic interference (EMI) and radio frequency interference (RFI), ensuring stable signal transmission, especially suitable for scenarios with high signal integrity requirements.

Low loss and good high-frequency characteristics
Using high-quality conductors and low-loss insulation materials, the cable performs well in the range of hundreds of MHz to GHz, meeting the needs of modern communications, radar, radio and other high-frequency equipment.

Flexible and durable
The braided cable has both flexibility and mechanical strength, suitable for environments that require bending, movement or frequent installation.

Application fields
Due to its outstanding performance, 50 Ohm Braiding Cable plays an important role in multiple industries and application scenarios, including but not limited to:

RF communication equipment
Widely used in antenna feeder systems in radio base stations, microwave communications, and mobile communication equipment.

Test and measurement instruments
