The **W2CA-131-R2** is a specific part number typically associated with high-performance **RF/Microwave Coaxial Cables**, often utilized in telecommunications, aerospace, and test-and-measurement equipment. It is frequently identified as a part of the "W2" series high-frequency cable assemblies. --- ### 1. Technical Specifications Below are the general electronic and physical characteristics typical of this component: | Feature | Specification (Typical) | | :--- | :--- | | **Cable Type** | Coaxial (Flexible or Semi-Rigid) | | **Impedance** | 50 Ohms (Standard RF) | | **Frequency Range** | DC to 18 GHz (Varies by connector) | | **Attenuation** | Low Loss (Specific to length) | | **Connector A** | SMA Male (Typically) | | **Connector B** | SMA Male (Typically) | | **Jacket Material** | FEP (Fluorinated Ethylene Propylene) | ### 2. Core Electronic Components A coaxial assembly like the W2CA-131-R2 consists of four primary electronic layers: 1. **Center Conductor:** Usually silver-plated copper or copper-clad steel. This carries the actual electrical signal. 2. **Dielectric:** A high-grade insulator (often PTFE) that maintains the spacing between the conductor and the shield to ensure stable impedance. 3. **Shielding:** A metallic braid or foil that protects the signal from Electromagnetic Interference (EMI) and prevents signal leakage. 4. **Outer Jacket:** Provides environmental protection and mechanical durability. --- ### 3. Key Electronic Characteristics * **VSWR (Voltage Standing Wave Ratio):** This part is designed for low VSWR, meaning it minimizes signal reflections. For a high-quality R2 variant, VSWR is usually below **1.35:1** at high frequencies. * **Propagation Velocity:** High-speed signal transmission, usually around **70% to 85%** of the speed of light, depending on the dielectric material. * **Power Handling:** Designed to handle moderate RF power levels without overheating the dielectric. ### 4. Common Applications * **Laboratory Testing:** Connecting signal generators to oscilloscopes or spectrum analyzers. * **Wireless Infrastructure:** Internal wiring for base stations or small cells. * **Military/Aerospace:** Used in radar systems where signal integrity is critical.
