The **CA-RSPNMA002** is a specialized radio frequency (RF) coaxial cable assembly typically used for bridging wireless communication devices to external antennas. Below is a detailed breakdown of its electronic components and technical specifications. --- ## 1. Component Breakdown | Component | Description | Material / Construction | | :--- | :--- | :--- | | **Connector A** | RP-SMA Male | Gold-plated brass with a center hole (Reverse Polarity). | | **Connector B** | N-Type Male | Nickel-plated brass with a center pin. | | **Coaxial Cable** | LMR-195 (or equivalent) | Low-loss double shielded 50-ohm cable. | | **Impedance** | 50 Ohms | Standard for RF and microwave transmissions. | --- ## 2. Technical Specifications ### RF Performance * **Frequency Range:** DC to 6 GHz (optimized for 2.4 GHz and 5.8 GHz WiFi bands). * **VSWR (Voltage Standing Wave Ratio):** Typically $\le$ 1.35:1 up to 3 GHz. * **Insertion Loss:** Dependent on length, but LMR-195 cables generally lose ~0.4 dB per meter at 2.4 GHz. ### Physical Characteristics * **Outer Diameter:** ~4.95 mm (0.195 inches). * **Minimum Bend Radius:** 12.7 mm (Static) to 50.8 mm (Dynamic). * **Operating Temperature:** -40°C to +85°C. --- ## 3. Key Electronic Functions ### Reverse Polarity SMA (RP-SMA) The RP-SMA Male connector is the standard interface for consumer-grade WiFi equipment (routers, access points). Unlike standard SMA, the "Male" connector has a threaded nut but a **female socket** center contact to comply with FCC regulations intended to prevent users from connecting high-gain antennas. ### N-Type Connector The N-Male connector is a rugged, weather-resistant interface used for professional-grade antennas, surge protectors, and outdoor enclosures. It features a threaded coupling mechanism that provides a secure, vibration-resistant connection. ### Shielding Effectiveness The cable utilizes a dual-shielding architecture: 1. **Inner Shield:** Aluminum foil tape (100% coverage). 2. **Outer Shield:** Tinned copper braid (~90% coverage). This combination prevents electromagnetic interference (EMI) and ensures signal integrity by minimizing "leakage" from the cable. --- ## 4. Typical Applications * Connecting a WiFi Router (RP-SMA) to an outdoor Yagi or Omni antenna (N-Female). * Bridging wireless bridge systems to lightning surge arrestors. * Internal wiring for RF test benches.
