The **W2CA-141-R2/N** is a specialized high-performance coaxial cable assembly primarily used in telecommunications, testing equipment, and high-frequency signal transmission applications. Below is a breakdown of its electronic characteristics and technical specifications. --- ### 1. Technical Specifications Table | Feature | Specification | | :--- | :--- | | **Component Type** | Coaxial Cable Assembly | | **Impedance** | 50 Ohms (Standard for RF) | | **Frequency Range** | DC up to 18 GHz (Typical for 141-series) | | **Connector Type** | N-Type (Male/Female depending on specific suffix) | | **Cable Type** | RG-141 / Semi-Flexible (Hand-formable) | | **Outer Diameter** | ~0.141 inches (3.58 mm) | | **Jacket Material** | FEP (Fluorinated Ethylene Propylene) | --- ### 2. Key Electronic Parts & Construction The performance of this assembly is determined by its internal layers: #### A. Center Conductor * **Material:** Silver-plated Copper Clad Steel (SPCCS). * **Function:** Carries the high-frequency signal. The silver plating minimizes skin effect losses at high frequencies. #### B. Dielectric (Insulator) * **Material:** PTFE (Polytetrafluoroethylene). * **Function:** Maintains the spacing between the inner and outer conductors to ensure constant **50 Ohm impedance**. It has a low dielectric constant to reduce signal attenuation. #### C. Outer Shielding * **Material:** Tin-soaked copper braid or seamless tubing. * **Function:** Provides 100% RF shielding (Electromagnetic Interference protection). Because it is "141" type, it is often **semi-rigid** or **hand-formable**, allowing it to hold its shape after bending. #### D. Connectors (N-Type) * The "N" in the part number refers to the **Type N connector**, a threaded, weatherproof connector. It is valued for its mechanical durability and ability to handle high power levels compared to SMA connectors. --- ### 3. Application Use Cases * **Base Stations:** Used in cellular infrastructure for connecting antennas to transmitters. * **Laboratory Testing:** Ideal for RF testing environments where low loss and high shielding are required. * **Military/Aerospace:** Due to the FEP jacket and PTFE dielectric, it can withstand high temperature ranges and harsh environments. ---
