18 GHz Economy Low-Loss RF Cable E52

Engineering Note

The E52 is an 18 GHz economy low-loss flexible RF coaxial cable designed for internal telecom cabinet routing, base-station connections, module interconnection, and general RF paths where cost-effective transmission is required. Its silver-plated copper inner conductor, LD PTFE dielectric, aluminum foil inner shield, silver-plated copper braid outer shield, and 5.20 mm blue FEP jacket provide a balanced structure for fixed internal RF connectivity. The cable supports DC–18 GHz operation, 1500 V.DC dielectric withstand voltage, and >70 dB shielding effectiveness for economy-grade RF interconnect applications without strict PIM constraints.
