The **CA-RSPNFBA010** is a specialized RF (Radio Frequency) coaxial cable assembly typically used in wireless networking, telecommunications, and industrial signal transmission. It is primarily designed to connect devices using different connector standards while maintaining low signal loss. --- ### 1. Technical Specifications The part number describes a specific configuration of connectors and cable types. | Feature | Specification | | :--- | :--- | | **Connector A** | RP-SMA (Reverse Polarity SMA) Male | | **Connector B** | N-Type Female (Bulkhead) | | **Cable Type** | LMR-195 (or equivalent low-loss coaxial) | | **Impedance** | 50 Ohms | | **Length** | Typically 10 feet (indicated by the '010' suffix) | | **Frequency Range** | DC to 6 GHz | --- ### 2. Breakdown of Components #### A. RP-SMA Male Connector * **RP (Reverse Polarity):** Unlike standard SMA, the pin and socket are swapped. This is a common standard for Wi-Fi equipment (routers, APs) to comply with FCC regulations. * **Male:** Features internal threads and a center socket (due to RP configuration). #### B. N-Type Female Bulkhead * **N-Type:** A large, rugged threaded connector capable of handling higher power and weather exposure. * **Bulkhead:** Includes a nut and washer, allowing the connector to be mounted through a hole in an enclosure or panel, creating a permanent port. #### C. LMR-195 Coaxial Cable * **Shielding:** Double-shielded to prevent EMI (Electromagnetic Interference). * **Loss Profile:** Much lower attenuation compared to standard RG-58 cable, making it ideal for longer runs in the 2.4GHz and 5GHz bands. --- ### 3. Common Applications This assembly acts as a "pigtail" or adapter cable for the following scenarios: 1. **Enclosure Mounting:** Connecting an internal Wi-Fi card (RP-SMA) to an external antenna mounted on the outside of a metal weather-proof box. 2. **Antenna Conversion:** Adapting a standard indoor router to a high-gain outdoor N-Type antenna. 3. **Industrial IoT:** Connecting cellular or LoRaWAN gateways to external mast-mounted antennas. ---
