The **PE9930-72-R** is a high-performance, specialized RF cable assembly typically manufactured by **Pasternack**. This specific part belongs to a family of high-frequency flexible cables designed for testing, instrumentation, and aerospace applications where signal integrity is critical. --- ### 1. Technical Specifications The part number "PE9930-72-R" provides specific data regarding its build and length. | Feature | Specification | | :--- | :--- | | **Cable Type** | PE-P160 (LL160 Equivalent) | | **Connector A** | N-Type Male | | **Connector B** | N-Type Male | | **Length** | 72 Inches (6 Feet) | | **Maximum Frequency** | Up to 18 GHz | | **Impedance** | 50 Ohms | | **Jacket Material** | FEP (Fluorinated Ethylene Propylene) | | **RoHS Compliant** | Yes (Indicated by "-R") | --- ### 2. Physical Construction The internal electronic components of the cable are layered to minimize loss and electromagnetic interference (EMI). * **Center Conductor:** Usually silver-plated copper (solid or stranded) for maximum conductivity. * **Dielectric:** Expanded PTFE (Polytetrafluoroethylene), which provides a low dielectric constant and low loss tangent. * **Shielding:** A multi-layer shield (typically a silver-plated copper tape followed by a silver-plated copper braid) to ensure >90 dB of RF shielding. * **Connectors:** Precision-machined N-Type connectors with gold-plated center contacts to minimize contact resistance. --- ### 3. Key Performance Characteristics * **Low Insertion Loss:** Designed to transmit signals over the 72-inch span with minimal power drop. * **Phase Stability:** The PE-P160 series is known for being "phase stable," meaning the phase of the signal does not shift significantly when the cable is bent or moved. * **Durability:** The FEP jacket is resistant to chemicals, UV light, and extreme temperatures, making it suitable for both lab environments and field deployments. --- ### 4. Common Applications Due to its 18 GHz rating and N-Type connectors, this assembly is commonly used in: 1. **Vector Network Analyzer (VNA) Testing:** Connecting devices under test to measurement equipment. 2. **Military Communications:** High-reliability RF links in ground and airborne systems. 3. **Cellular Infrastructure:** Testing and deploying 5G and LTE base station hardware. ---
