The part number **CA-RSPNFBCN19** typically refers to a high-quality RF (Radio Frequency) coaxial cable assembly. These are commonly used to connect wireless equipment, such as cellular boosters, Wi-Fi routers, or GPS systems, to external antennas. --- ## 1. Technical Specifications The components of this cable assembly are designed for low signal loss and durability in outdoor or industrial environments. | Component | Description | | :--- | :--- | | **Connector A** | **RP-SMA Male** (Reverse Polarity SMA) | | **Connector B** | **N-Female Bulkhead** | | **Cable Type** | **195-Series** (Equivalent to LMR-195) | | **Impedance** | 50 Ohms | | **Frequency Range** | DC up to 6 GHz | --- ## 2. Key Electronic Features ### A. Connector Details * **RP-SMA Male:** This is a "Reverse Polarity" connector often found on Wi-Fi equipment (access points and routers). The male side has threads on the inside but a female-style center socket. * **N-Female Bulkhead:** The "N" type is a larger, ruggedized connector suitable for outdoor use. The "Bulkhead" design includes a nut and washer, allowing the connector to be mounted through a hole in a wall or enclosure, acting as a weatherproof pass-through point. ### B. 195-Series Coaxial Cable The "19" in the part number often indicates the cable type (195). * **Low Loss:** It offers significantly better performance (less signal attenuation) than standard RG-58 cable. * **Shielding:** Usually features double shielding (aluminum foil + tinned copper braid) to protect against Electromagnetic Interference (EMI). * **Flexibility:** It has a diameter of roughly 0.195 inches, making it flexible enough for tight routing while remaining durable. ### C. Signal Integrity * **VSWR (Voltage Standing Wave Ratio):** Designed to maintain a low VSWR (typically < 1.35:1), ensuring that most of the power reaches the antenna rather than reflecting back to the source. --- ## 3. Common Applications * **Enclosure Mounting:** Installing a radio inside a metal box while mounting the antenna on the outside. * **Wi-Fi Extensions:** Connecting a standard Wi-Fi router to a high-gain outdoor antenna. * **IoT/M2M:** Used in industrial gateways for cellular (LTE/5G) or LoRaWAN communication. ---
