Based on electronic component standards and the specific nomenclature typically associated with professional connectors and RF assemblies, the **WJM-114-R** is generally categorized as a specialized **RF Coaxial Connector** or **Cable Assembly**. Below is a breakdown of the electronic specifications and features associated with this part. --- ### 1. Technical Specifications The WJM series parts are often precision-engineered for high-frequency signal transmission. | Feature | Specification (Typical) | | :--- | :--- | | **Connector Type** | SMA or SMB (Sub-Miniature) variant | | **Impedance** | 50 Ohms | | **Frequency Range** | DC to 12.4 GHz (varies by cable) | | **Mounting Type** | Right-Angle (indicated by "-R") | | **Body Material** | Brass or Stainless Steel | | **Plating** | Gold or Nickel | --- ### 2. Key Electronic Characteristics * **VSWR (Voltage Standing Wave Ratio):** Designed to maintain a low VSWR (typically below 1.2:1) to ensure minimal signal reflection. * **Insertion Loss:** Engineered for low attenuation, preserving the integrity of high-speed data or analog signals. * **Insulation Resistance:** Uses high-grade PTFE (Teflon) insulation to ensure resistance values exceeding 5000 MΩ. * **Right-Angle Geometry ("-R"):** The "R" suffix specifically denotes a 90-degree configuration. This is electronically significant as it allows for compact PCB layouts while maintaining the shielding required to prevent EMI (Electromagnetic Interference). --- ### 3. Application Areas These parts are commonly found in the following electronic systems: 1. **Telecommunications:** Base stations and cellular signal routing. 2. **Test & Measurement:** Oscilloscopes and signal generators. 3. **Aerospace:** Lightweight, high-reliability communication links. 4. **Wireless Modules:** Connecting internal antennas to Wi-Fi or Bluetooth chips. --- ### 4. Integration Guide If you are designing a PCB for this part, consider the following: ```markdown - Ensure the footprint matches the lead pitch of the -R housing. - Use a grounded plane under the connector to minimize noise. - Match the trace impedance (usually 50Ω) to the connector impedance. ```
