The N Female to SMA Male Cable Assembly is a crucial solution for system integrators, engineers, and technicians needing to connect equipment featuring the rugged, larger N-Type connector to devices utilizing the smaller, widely common SMA connector. This assembly uses premium RG316 coaxial cable, ensuring a reliable, low-loss interconnect solution across a wide range of frequencies.
This adapter cable is indispensable in laboratories, telecommunications, and industrial settings where compatibility between professional-grade equipment and standard commercial radio modules is required.
Key Features and Components
1. High-Quality RG316 Coaxial Cable
Broadband Performance: The RG316 coaxial cable is known for its excellent performance up to high frequencies (typically into the multi-GHz range), making it suitable for applications spanning from low-frequency radio to Wi-Fi, GPS, 3G/4G/5G Cellular, and Bluetooth.
Temperature Stability: RG316 utilizes a PTFE dielectric, offering superior temperature stability compared to cables using polyethylene dielectrics (like RG58 or RG174). This makes the cable highly reliable in environments subject to heat variations.
Flexibility and Durability: Despite its small diameter (approx. 2.5 mm), the RG316 offers good flexibility and features a plated outer conductor (braid), providing robust shielding and high durability for repeated bending and handling.
Premium Connector Interfaces
N Female Connector: The N-Type connector is a robust, threaded, medium-sized connector widely used in professional radio frequency applications, particularly in base stations, high-power antennas, and industrial equipment.3 The Female configuration is designed to connect to the Male port on an antenna or device.
SMA Male Connector: The SMA (Sub-Miniature A) connector is an industry-standard, screw-on connector used on most small radio modules, GPS receivers, cellular modems, and test equipment.4 The Male configuration connects to the Female port on a radio module or device.
Impedance Match: All components are precisely matched to $50\ \Omega$ impedance, minimizing Voltage Standing Wave Ratio (VSWR) and maximizing power transfer efficiency across the cable link.
Versatile Application Scenarios (Use Cases)
This adapter cable assembly bridges the gap between different connectivity standards, making complex setups possible:
1. Laboratory and Test Environments
Bench Testing: Essential for connecting standard lab equipment (often using N-Type ports) such as spectrum analyzers or network analyzers to the smaller SMA ports found on circuit boards, development kits, and RF modules for characterization and testing.
2. Telecommunications and Cellular
Antenna Integration: Used to connect larger, outdoor N-Female antennas (e.g., high-gain cellular or LoRa antennas) to the SMA-equipped ports of cellular modems, routers, or industrial gateways installed indoors.
Signal Amplification: Facilitates the hook-up between in-line signal boosters, repeaters (N-Type ports), and end-user devices (SMA ports).
3. GPS and Timing Systems
4. Industrial IoT (IIoT)
SEO and Performance Advantage
The use of RG316 is a critical performance differentiator. Unlike common adapter cables using materials like RG174, the PTFE-based RG316 offers a higher maximum operating frequency and better temperature stability, leading to more reliable, lower-loss connections, especially in high-power or high-temperature applications.
By providing a robust, professionally assembled interface between N Female and SMA Male connectors, this cable assembly ensures your sophisticated RF equipment performs optimally.
