Micro Coaxial Cable-Micro Coaxial Cable factory-(FRS)-FRS
Voltage Standing Wave Ratio (VSWR) is a crucial measurement in radio frequency (RF) engineering. It tells us how efficiently RF power travels from a source (like a transmitter) through a cable to its destination (like an antenna) without significant power loss due to reflections. Simply put, it measures the match (or mismatch) between the cable’s impedance and the impedance of the devices it connects.
What Does VSWR Mean?
Micro Coaxial Cables: The Tiny RF Workhorses
Micro coax cables are characterized by their extremely small outer diameter (OD), typically ranging from approximately 0.5 mm (0.02 inches) up to around 2.2 mm (0.087 inches). They often require specialized connectors for termination. Their miniature size makes them indispensable in compact, high-frequency applications such as:
Typical VSWR Range for Quality Micro Coax
For high-quality micro coaxial cables operating within their specified frequency range and properly terminated, the typical VSWR range is between 1.1:1 and 1.5:1.
Factors Affecting Micro Coax VSWR:
Micro Coax vs. Standard Coax Performance: (Example Frequency Ranges)
| Feature | High-Quality Micro Coax (e.g., 1.13mm, 1.37mm OD) | Standard RG Coax (e.g., RG174, RG316) | Micro-Coax Advantage |
|---|---|---|---|
| Typical VSWR | 1.1:1 – 1.5:1 | 1.3:1 – 1.7:1+ | Lower reflection loss, better match |
| Signal Loss | Higher (Due to small conductors) | Lower | N/A |
| Diameter | ~0.5mm – 2.2mm | ~2.5mm – 10mm+ | Fits tight spaces, less weight |
| Max Frequency | Often up to 20 GHz or higher | Usually up to 3-6 GHz | Supports much higher frequencies |
| Flexibility | Very High (Typically) | Moderate | Better for dynamic routing/bending |
| Common Use | Smartphones, Drones, Medical Devices | Test Equipment, Base Stations | Mission-critical in compact devices |
Choosing Micro Coax: What VSWR Should You Look For?
In Summary:
For high-performance applications demanding efficiency and reliability, expect quality micro coaxial cable assemblies to deliver VSWR between 1.1:1 and 1.5:1. Values consistently below 1.3:1 indicate exceptional performance for these miniature cables. Achieving this requires quality components and meticulous installation. Understanding and verifying VSWR is fundamental to ensuring the success of your micro-coaxial RF connections.
