50ohm RG393 Flexible High-Power Microwave Coaxial Cable for RF signal applications

M17/127-RG393 | 50Ω | 11 GHz | 4500W @ 0.1 GHz | 5000 VRMS | -55°C to +200°C

The RG393 is a flexible high-power 50Ω microwave coaxial cable engineered for systems that must deliver high RF power without sacrificing routing flexibility. With a 2.39 mm stranded silver-plated copper inner conductor, a double braid of silver-plated copper wire, and an extruded FEP jacket, it delivers up to 4500 W at 0.1 GHz, 1100 W at 1 GHz, and reliable performance up to 11 GHz. Weighing just 260 g/m and featuring a 9.9 mm outer diameter, the RG393 is significantly lighter and more flexible than traditional rigid high-power microwave cables. Its stranded conductor resists vibration and flex fatigue, making it ideal for shipboard radar, airborne microwave links, and mobile high-power systems where routing flexibility and maintenance access are critical.
