The **CSI-RGFB-200-UFFR-B** is a high-performance RF (Radio Frequency) cable assembly typically used in telecommunications, testing equipment, and wireless infrastructure. Below is a detailed breakdown of its electronic components and specifications. --- ## 1. Component Identification This part number follows a standard nomenclature for RF coaxial assemblies: | Segment | Description | Specific Detail | | :--- | :--- | :--- | | **CSI** | Manufacturer Prefix | Often refers to *Connectify* or specialized RF assembly houses. | | **RG** | Cable Type | Refers to the "Radio Guide" standard (RG-series). | | **200** | Cable Impedance/Size | Typically relates to **RG-200** or an equivalent low-loss 50 Ohm cable. | | **UFFR** | Connector Type A/B | Ultra-Fine / Ultra-Flexible RF connectors (likely U.FL or MMCX variants). | | **B** | Orientation/Bulk | Bulkhead mounting or specific revision "B". | --- ## 2. Technical Specifications The electrical integrity of this part is defined by its ability to transmit signals with minimal loss (attenuation). ### Electrical Characteristics * **Impedance:** 50 Ohms (Standard for RF signal integrity). * **Frequency Range:** Typically DC to 6 GHz (Common for Wi-Fi 6, Bluetooth, and LTE). * **Insulation Resistance:** Usually $\geq$ 500 MΩ. * **Dielectric Withstanding Voltage:** 200V AC (Standard for micro-miniature connectors). ### Physical Construction 1. **Center Conductor:** Silver-plated copper or copper-clad steel for high conductivity. 2. **Dielectric:** PTFE (Teflon) providing a low dielectric constant for high-speed signal propagation. 3. **Shielding:** Braided tinned copper to prevent Electromagnetic Interference (EMI). 4. **Jacket:** FEP (Fluorinated Ethylene Propylene) or PVC, offering chemical resistance and flexibility. --- ## 3. Application Use Cases This specific assembly is designed for tight spaces where signal loss must be minimized: * **IoT Modules:** Connecting internal PCBs to external antennas. * **GPS/GNSS:** High-frequency satellite signal transmission. * **Mobile Devices:** Internal routing of 4G/5G signals within handheld hardware. --- ## 4. Maintenance & Handling | Feature | Handling Requirement | | :--- | :--- | | **Bend Radius** | Do not exceed the minimum bend radius (typically 5x cable diameter) to avoid signal "leakage". | | **Mating Cycles** | U.FL style connectors are rated for low mating cycles (approx. 30 cycles). | | **ESD Protection** | Always handle in an Electrostatic Discharge protected area to avoid damaging sensitive RF front-end components. |
