18 GHz Compact Economy Low-Loss RF Cable E36

Engineering Note

The E36 is an 18 GHz compact economy low-loss flexible RF coaxial cable designed for dense telecom cabinet routing, base-station internal connections, module interconnection, and general RF paths where compact size and cost-effective transmission are required. Its silver-plated copper inner conductor, LD PTFE dielectric, aluminum foil inner shield, silver-plated copper braid outer shield, and 3.60 mm blue FEP jacket provide a compact structure for internal RF connectivity. The cable supports DC–18 GHz operation, 1000 V.DC dielectric withstand voltage, and >70 dB shielding effectiveness for economy-grade RF routing where strict PIM requirements are not the main constraint.
