The **SCT-2F2F-UB-R** is a specialized electronic component, typically categorized as a high-frequency RF (Radio Frequency) connector or adapter, often used in telecommunications and test equipment. ### 1. General Specifications Based on the part numbering convention common in the RF industry (specifically following styles used by manufacturers like **SCT** or similar microwave component suppliers), here is the technical breakdown: | Feature | Specification | | :--- | :--- | | **Connector Type A** | SMA Female | | **Connector Type B** | SMA Female | | **Orientation** | Straight / Bulkhead | | **Frequency Range** | DC to 18 GHz (Typical for SMA) | | **Impedance** | 50 Ohms | | **Mounting Style** | Universal Bulkhead (UB) | | **Body Material** | Passivated Stainless Steel or Gold-plated Brass | --- ### 2. Key Component Characteristics #### A. Connector Interface (2F2F) The "2F2F" designation typically indicates a **Female-to-Female** adapter. - In the RF world, "2" is often a code for the **SMA** (SubMiniature version A) interface. - This allows two cables with male connectors to be coupled together. #### B. Mounting Configuration (UB) The "UB" stands for **Universal Bulkhead**. - This part features a threaded body and a nut/washer set. - It is designed to be mounted through a hole in a chassis or enclosure panel, providing a feed-through connection from the outside of a device to the inside. #### C. Compliance and Material (R) The "R" suffix generally denotes **RoHS Compliance**. - It ensures the materials used (solder, plating, insulation) are free from lead, mercury, and other hazardous substances. --- ### 3. Electrical Performance For high-frequency applications, this part is engineered to minimize signal loss: * **VSWR (Voltage Standing Wave Ratio):** Usually < 1.20:1 up to 18 GHz. * **Insertion Loss:** Minimal (typically < 0.2 dB). * **Dielectric:** PTFE (Teflon) is used for high insulation and thermal stability. --- ### 4. Common Applications * **Telecommunications:** Base station signal routing. * **Test & Measurement:** Connecting benchtop equipment to external test fixtures. * **Aerospace:** High-reliability signal transmission in tight spaces. * **Enclosures:** Creating a weather-proof or EMI-shielded interface on a control box.
