Precision Signal Integrity for Professional RF Systems
This SMA Male to SMA Male RG142 coaxial patch cable is engineered for mission-critical RF environments where signal purity is non-negotiable. Designed with a consistent 50 Ohm impedance, it facilitates seamless high-frequency transmission across a broad spectrum. Whether utilized in laboratory testing, wireless infrastructure, or telecommunications, this assembly minimizes Return Loss and ensures your system operates at peak efficiency without electromagnetic interference.
Rugged RG142 Double-Shielded Construction
Unlike standard RG316 or RG174 cables, the RG142 cable featured in this assembly offers significantly higher power handling and superior shielding. It boasts a double-braided shield that provides exceptional isolation against EMI/RFI, making it perfect for high-density electronic environments. The robust design ensures that your data remains secure and your signal remains clear, even when routed alongside other high-powered equipment.
Industrial-Grade Durability and Heat Resistance
The distinctive copper-colored jacket is crafted from high-grade PTFE (Teflon), offering industry-leading thermal stability. This cable is capable of withstanding extreme temperature fluctuations ranging from -55°C to +200°C, making it the primary choice for aerospace, automotive, and industrial applications. Its durability ensures long-term reliability in harsh environments where standard PVC-jacketed cables would fail.
Premium Gold-Plated SMA Connectors
Our SMA Male (Plug) connectors are precision-machined from high-quality brass with thick gold plating. This finish not only provides a luxurious aesthetic but, more importantly, prevents oxidation and ensures thousands of mating cycles with minimal contact resistance. The knurled interface allows for easy, secure finger-tightening, providing a gas-tight connection that protects your delicate RF sensitive equipment.
Wide-Ranging Application Versatility
This versatile RF jumper cable is the ideal solution for various high-tech sectors, including:
Aviation & Aerospace: Onboard communication systems and radar equipment.
Telecommunications: 4G/5G LTE base stations and signal boosters.
WiFi & Wireless Networking: High-gain antenna connections and router patching.
Medical Electronics: Precision signal transmission in diagnostic and imaging devices.
RF Testing: Interconnecting spectrum analyzers, signal generators, and oscilloscopes.
