SMA Male to SMA Male RG142 Cable Assembly
High-Temperature Precision RF Jumper Assembly
Terminated with secure threaded SMA Male connectors on both ends, this high-temperature 50-Ohm cable assembly utilizes premium RG142 coaxial cable. Featuring a solid PTFE dielectric, double silver-plated copper braid shields (≥ 90 dB isolation), and a brown FEP jacket, it operates reliably from -55°C to +200°C. Rated up to 8 GHz, it is engineered for aerospace avionics, radar arrays, and high-reliability microwave interconnects.
