The **CONREVSMA012-R58** is a high-performance RF connector manufactured by Linx Technologies (now part of TE Connectivity). It is specifically a **Reverse Polarity SMA (RP-SMA) female jack** designed for cable mounting. --- ### 1. Technical Specifications The following table summarizes the core electronic and physical attributes of the component: | Characteristic | Specification | | :--- | :--- | | **Connector Type** | RP-SMA Female (Jack) | | **Mounting Type** | Cable Mount (Crimp) | | **Impedance** | 50 $\Omega$ | | **Frequency Range** | 0 to 12.4 GHz | | **Cable Group** | RG-58, LMR-195 | | **Body Finish** | Gold Plated | | **Contact Material** | Beryllium Copper | | **Dielectric** | PTFE (Teflon) | --- ### 2. Key Design Features * **Reverse Polarity (RP):** Unlike a standard SMA female (which has a socket/hole), a Reverse Polarity SMA female has a **male pin center contact**. This is a safety and regulatory design often used in Wi-Fi equipment to prevent the connection of high-gain professional antennas to consumer devices. * **RG-58 Compatibility:** The "R58" suffix indicates it is optimized for RG-58 coaxial cables. These cables are common in mid-range RF applications due to their balance between flexibility and signal loss. * **Gold Plating:** The body and center contact are gold-plated to ensure excellent conductivity and resistance to corrosion over time, which is critical for maintaining signal integrity in high-frequency applications. --- ### 3. Common Applications * **Wi-Fi Routers and Access Points:** Most consumer Wi-Fi equipment uses RP-SMA for antenna connections. * **LoRaWAN/IoT Gateways:** Used for external antenna extensions. * **RF Prototyping:** Ideal for custom cable assemblies where a robust, threaded connection is required. * **LMR-195 Assemblies:** Often used with LMR-195 cable for lower signal loss over longer distances compared to standard RG-58. --- ### 4. Assembly Overview To install this connector, a **crimp tool** is required. The assembly typically follows these steps: 1. Strip the RG-58 cable to specific dimensions (jacket, braid, and dielectric). 2. Solder or crimp the center pin onto the cable's inner conductor. 3. Insert the pin/cable into the connector body. 4. Slide the crimp ferrule over the braid and use a hex-crimp tool to secure the assembly.
