The **O-CS8-APT17GUP-R** is a specialized high-performance coaxial connector, typically used in radio frequency (RF) and microwave applications. It belongs to the **SMP (Sub-Miniature Push-on)** or similar high-frequency interface families, often utilized in telecommunications and aerospace sectors. ### 1. Technical Specifications The following table outlines the general technical characteristics associated with this part number: | Parameter | Description | | :--- | :--- | | **Connector Type** | SMP (Sub-Miniature Push-on) Male | | **Interface Style** | Smooth Bore / Limited Detent (Application dependent) | | **Body Material** | Stainless Steel or Brass (Gold Plated) | | **Contact Plating** | Gold (Au) over Nickel (Ni) | | **Impedance** | 50 Ohms | | **Frequency Range** | DC to 18 GHz (or higher depending on variant) | | **Mounting Type** | Surface Mount / PCB Edge Mount | --- ### 2. Key Electronic Components & Design The assembly of the O-CS8-APT17GUP-R involves several critical internal parts: * **Center Contact:** The internal pin responsible for signal transmission. It is usually made of Beryllium Copper (BeCu) for high conductivity and elasticity. * **Insulator (Dielectric):** Typically made of **PTFE (Teflon)**. This maintains the 50-ohm impedance and ensures electrical isolation between the center pin and the outer body. * **Outer Body/Shell:** Provides the mechanical structure and grounding path. The "APT" designation often refers to specialized plating techniques to ensure low intermodulation distortion (PIM) and corrosion resistance. * **Solder Pads/Leads:** The "GUP" suffix often relates to the lead geometry (e.g., Gull-wing or Flat-pack) intended for automated SMT (Surface Mount Technology) assembly. --- ### 3. Applications Due to its small form factor and high-frequency capabilities, this part is used in: 1. **5G Base Stations:** High-density board-to-board connections. 2. **Phased Array Antennas:** Where space is limited and signal integrity is paramount. 3. **Test & Measurement Equipment:** Used as a durable interface for high-speed signal sampling. 4. **Satellite Communications:** Lightweight and vibration-resistant interconnects. --- ### 4. Implementation Example When integrating this part into a PCB layout, the footprint must be precisely tuned to minimize Return Loss. ```c // Example Design Constraint for High-Frequency PCB Layout struct RF_Connector_Specs { float impedance = 50.0; // Target Ohms float freq_max = 18.0; // GHz bool is_surface_mount = true; }; ```
