The **W2PA-14WB-R2/N** is a specialized high-performance coaxial connector, commonly used in RF (Radio Frequency) and microwave applications. It belongs to the **SMP series** (Sub-Miniature Push-on) family, specifically designed for high-density, board-to-board, and blind-mate connections. ### 1. Key Technical Specifications The following table highlights the primary electrical and mechanical characteristics of this component: | Feature | Specification | | :--- | :--- | | **Series** | SMP (Sub-Miniature Push-on) | | **Interface Type** | Male (Plug) | | **Detent Level** | Full Detent (Secure locking) | | **Mounting Type** | Surface Mount (SMT) / PCB Mount | | **Impedance** | 50 Ohms | | **Frequency Range** | DC to 40 GHz (typical for high-grade SMP) | | **Termination** | Solder / Reflow compatible | --- ### 2. Functional Breakdown of Parts #### A. The Housing (Body) The body is typically constructed from **Gold-plated Beryllium Copper** or Stainless Steel. Gold plating is essential in RF components to minimize skin effect losses and prevent oxidation over time, ensuring a stable signal path. #### B. The Center Contact (Pin) This is the core conductive element. In the W2PA-14WB-R2/N, the pin is engineered for high-frequency signal integrity. It must maintain a precise geometry to ensure the 50-ohm characteristic impedance is constant, preventing signal reflections (VSWR). #### C. The Dielectric (Insulator) Usually made of **PTFE (Teflon)**. This material acts as the insulator between the center pin and the outer body. It is chosen for its low dielectric constant and high thermal stability, which is critical during the soldering process. #### D. The Detent Mechanism As a "Full Detent" connector, the internal geometry includes a locking lip. When the female (cabled) connector is pushed on, it "snaps" into place. This provides high retention force, making it suitable for environments with high vibration or shock. --- ### 3. Application Use Cases This specific part is often found in high-tech infrastructure including: * **Phased Array Antennas:** Due to the small footprint. * **Test and Measurement:** High-frequency oscilloscopes and signal generators. * **Aerospace & Defense:** Radar systems and satellite communication modules. * **Optical Networking:** High-speed data transceivers. --- ### 4. Footprint Example (Generic SMT) While exact dimensions should be verified via the manufacturer's datasheet, the PCB layout typically follows this logic: ```markdown [Signal Pad] -> Center Pin [GND Pads] -> Outer Body (usually 4 surrounding pads) ```
