The **CONREVSMA014-R178** is a high-quality RF (Radio Frequency) 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 mechanical characteristics of the component: | Feature | Specification | | :--- | :--- | | **Connector Type** | RP-SMA Female (Jack) | | **Mounting Type** | Cable Mount (Crimp) | | **Cable Compatibility** | RG-178, RG-196 | | **Impedance** | 50 Ohms | | **Frequency Range** | 0 to 12.4 GHz | | **Insulation Resistance** | 5000 MΩ min | | **Voltage Rating** | 250V RMS | | **Body Material** | Brass (Gold Plated) | | **Contact Material** | Beryllium Copper (Gold Plated) | --- ### 2. Key Component Features #### A. Reverse Polarity (RP) Design Unlike a standard SMA connector, where the female jack has a socket and the male plug has a center pin, a **Reverse Polarity SMA** swaps the center contact. In this case, the "Female Jack" actually contains a **male pin** center contact. This is common in Wi-Fi and consumer wireless equipment to prevent the connection of high-gain professional antennas to unauthorized devices (per FCC regulations). #### B. Material Composition * **Gold Plating:** The body and contacts are gold-plated to ensure excellent conductivity and resistance to oxidation/corrosion over time. * **PTFE Insulator:** Uses high-grade Teflon (PTFE) to maintain consistent impedance across high frequencies. #### C. Cable Attachment This specific part number is designed for **RG-178 coaxial cable**. RG-178 is a very thin (approx. 1.8mm diameter), high-temperature cable often used in tight spaces like internal laptop antennas or small IoT devices. --- ### 3. Typical Applications * **Wi-Fi Routers:** Connection points for external dipole antennas. * **IoT Modules:** Providing an external antenna interface for LoRa, Zigbee, or Bluetooth modules. * **SDR (Software Defined Radio):** Used in compact RF front-ends. * **Drones/UAVs:** Lightweight RF telemetry and video transmission systems. ---
