Documentation
Performance & Technical Specifications
Engineered for stable RF performance, low signal loss, and long-term durability across demanding wireless and communication applications.
Wide Frequency Range
This RP-SMA Extension Cable supports a broad frequency spectrum from 10 MHz to 8000 MHz. The wide range ensures compatibility across low and high-frequency applications without compromising signal quality.
50Ω Impedance
Proper impedance matching is critical because it:
• Prevents signal reflection
• Maintains signal strength
• Protects connected equipment
• Ensures maximum power transfer
This guarantees seamless integration with most antennas and wireless devices.
Efficient Signal Transmission
With a Voltage Standing Wave Ratio (VSWR) of ≤1.2, the cable minimizes signal reflection between the source and antenna.
A lower VSWR means:
• Better transmission efficiency
• Reduced power loss
• Stronger and cleaner signal output
• Improved overall system performance
This makes the cable ideal for professional and industrial RF installations.
Signal Loss By Length
• 50 cm: ≤ 0.75 dB
• 100 cm: ≤ 1.40 dB
Using the right jumper length minimizes signal loss, ensuring high RF efficiency and consistently robust, reliable connections between radios and antennas.
Durable Construction & Temperature Resistance
Built for demanding environments, the cable operates within a wide temperature range of -40°C to +185°C, ensuring reliability in extreme heat or cold conditions.
With IP67 protection capability, it offers resistance against dust and temporary water exposure, making it suitable for both indoor and outdoor installations.
