The **CA3N-R** is a high-performance, precision N-type RF (Radio Frequency) connector, typically designed for use with high-quality coaxial cables (such as LMR-400 or similar low-loss cables). The "R" suffix usually denotes "Reverse Polarity" or specific "RoHS" compliance depending on the manufacturer, but in the context of standard RF components, it refers to a **Right-Angle** orientation. ### 1. Key Technical Specifications Below are the typical electronic and mechanical characteristics for a CA3N-R series connector: | Feature | Specification | | :--- | :--- | | **Connector Type** | N-Type (Male/Plug) | | **Body Style** | Right Angle (90°) | | **Impedance** | 50 Ohms (Standard) | | **Frequency Range** | DC to 11 GHz (varies by cable type) | | **Dielectric Withstanding** | ~2500V RMS | | **Contact Plating** | Silver or Gold | | **Body Material** | Brass with Tri-metal (Albaloy) or Nickel plating | --- ### 2. Functional Components The "parts" of a CA3N-R assembly typically consist of several precision-engineered elements: * **Main Body:** A 90-degree housing made of plated brass. The right-angle design is crucial for tight spaces where a straight cable exit would cause mechanical stress. * **Center Pin:** A conductive pin (usually gold-plated) that carries the signal. In a "Plug" configuration, this is the male pin. * **Dielectric Insulator:** Usually made of **PTFE (Teflon)**. This holds the center pin in place and maintains the 50-ohm impedance by providing a specific constant between the pin and the outer shell. * **Coupling Nut:** The threaded outer ring used to lock the connector onto a female bulkhead or jack. * **Outer Ferrule/Crimp Sleeve:** A metal tube used to secure the cable braid to the connector body, ensuring grounding and mechanical strength. --- ### 3. Common Applications Due to its rugged design and N-type interface, the CA3N-R is found in professional-grade wireless infrastructure: 1. **Cellular Base Stations:** Connecting antennas to amplifiers. 2. **Outdoor WiFi Systems:** High-power bridges and access points. 3. **Radio Testing Equipment:** Used where low insertion loss and high durability are required. 4. **Satellite Communications:** Handling microwave frequencies with minimal signal leakage. --- ### 4. Installation Note The "CA" prefix often suggests a **Crimp-on** attachment method. To install this part correctly, one must: 1. Strip the coaxial cable to specific dimensions. 2. Solder or crimp the center pin onto the cable's core wire. 3. Slide the ferrule over the cable braid and use a specialized hex-crimp tool to secure the assembly.
