Silver-plated EPDM (0.03–0.1mm thickness) dominates for 18–110 GHz systems, offering <0.05 dB insertion loss and 80°C thermal stability. Conductive fluoroelastomers (MIL-G-83528B) handle 40+ dB shielding in military radars. Install with 7–12 N·m torque on WR-90 flanges; replace every 5,000 operational hours in high-vibration environments. Material Requirements Last year, during the vacuum thermal cycling test of […]

Use waveguide flange covers during transport/storage (preventing 0.1–5 dB insertion loss from dust) or inactive system periods. Essential in corrosive environments (e.g., coastal 5G sites), they block moisture ingress per MIL-STD-348A. Install with torque-controlled bolts (12–15 N·m for WR-90) and replace every 6–12 months in high-humidity areas. Protection Requirements Last June, the AsiaStar 9 satellite
