The **RTS-2A14-R** is a specific type of **Reverse Polarity SMA (RP-SMA) Connector**, typically used in RF (Radio Frequency) applications. It is designed to be mounted on a PCB (Printed Circuit Board) to provide a connection point for antennas or coaxial cables. --- ### 1. Technical Specifications The following table summarizes the key electrical and physical characteristics of the RTS-2A14-R: | Feature | Specification | | :--- | :--- | | **Connector Type** | RP-SMA (Reverse Polarity SMA) | | **Gender** | Jack (Female body, but with a male center pin) | | **Mounting Type** | Through-Hole, Right Angle | | **Impedance** | 50 Ohms | | **Frequency Range** | 0 to 6 GHz (Typical for standard SMA) | | **Body Material** | Brass | | **Plating** | Gold (for better conductivity and corrosion resistance) | | **Orientation** | 90° (Right Angle) | --- ### 2. Key Components & Construction The RTS-2A14-R consists of several critical electronic and mechanical parts: 1. **Center Pin (Contact):** Unlike a standard SMA female (which has a socket), the **RP-SMA Jack** features a protruding male pin. This is the primary signal conductor. 2. **Dielectric Insulator:** Usually made of **PTFE (Teflon)**. This surrounds the center pin to maintain the 50-ohm impedance and prevent short-circuiting to the outer shell. 3. **Outer Shell/Body:** Made of gold-plated brass. This acts as the ground (shield) and provides the threaded interface for the mating connector. 4. **PCB Legs (Leads):** * **Signal Leg:** The center pin that passes through the board to carry the RF signal. * **Ground Legs:** Four corner legs that provide mechanical stability and ground the shield to the PCB ground plane. --- ### 3. Common Applications Due to its 50-ohm impedance and compact size, this part is widely used in: * **Wi-Fi Routers:** To connect external dipole antennas. * **IoT Gateways:** For LoRa, Zigbee, or cellular connectivity. * **RF Testing Equipment:** As a board-level interface for signal analysis. * **RC Transmitters:** Common in drone and hobbyist radio gear. --- ### 4. Mounting Diagram (Simplified) When designing a PCB for this part, the footprint usually follows this logic: ```text [ G ] [ G ] <-- Ground Through-Holes ( S ) <-- Center Signal Hole [ G ] [ G ] <-- Ground Through-Holes ``` ---
