The **W2PA-55F-R/N** is a specific electronic component belonging to the category of **High-Frequency Coaxial Connectors**, specifically an **SMPM** (Sub-Miniature Push-On Micro) series connector. These are typically used in RF (Radio Frequency) applications where space is limited and high performance is required. --- ### 1. Technical Specifications Below is a breakdown of the typical characteristics for this part series: | Feature | Description | | :--- | :--- | | **Connector Type** | SMPM (Mini-SMP) | | **Gender** | Female (Jack) | | **Body Orientation** | Straight | | **Impedance** | 50 Ohms | | **Frequency Range** | DC to 65 GHz (typically) | | **Mounting Type** | PCB Mount / Solder / Cable Mount (depends on variant) | | **Termination** | Surface Mount or Through-Hole | --- ### 2. Key Electronic Features #### A. High-Frequency Performance The "55" in the part number often refers to the optimized frequency range (up to 50-65 GHz). These parts are designed to maintain low **VSWR** (Voltage Standing Wave Ratio) and low insertion loss at extremely high frequencies. #### B. Push-On Coupling Unlike standard SMA connectors that require threading, the SMPM interface uses a **snap-on** or **push-on** mechanism. This allows for: * High-density packaging on PCBs. * Blind-mate capabilities (connecting without seeing the interface). * Compensation for axial and radial misalignment. #### C. Material Composition * **Body:** Usually Gold-plated Beryllium Copper or Stainless Steel. * **Center Contact:** Gold-plated for maximum conductivity and oxidation resistance. * **Insulator:** PTFE (Teflon) or high-performance polymers for dielectric stability. --- ### 3. Common Applications Due to its miniature size and high-frequency capabilities, the W2PA-55F series is commonly found in: 1. **Telecommunications:** 5G/6G infrastructure and high-speed backhaul. 2. **Military/Aerospace:** Radar systems and satellite communication. 3. **Test & Measurement:** High-speed oscilloscopes and signal generators. 4. **Computing:** High-speed server backplanes and optical modules. --- ### 4. Part Number Breakdown (Generalized) * **W2PA:** Series identifier (Manufacturer specific, often related to Wellshow or similar RF vendors). * **55F:** Likely denotes the frequency rating (50+ GHz) and "F" for Female/Jack. * **R/N:** Often refers to the plating or packaging (e.g., Gold over Nickel or RoHS compliance).
