RF Connectors

Product Overview

EIA & MEIA Series RF Connectors

Aptiv Interconnect's EIA (Electronic Industries Alliance) Series are the standard for high-power RF transmission in broadcast and cellular infrastructure. Characterized by their large size and flanged mounting, EIA connectors handle significant kilowatt power levels with minimal signal loss. The MEIA™ (Miniaturized EIA) Series is the next generation, offering equivalent power handling in a 30% smaller and 40% lighter form factor. MEIA connectors use a threaded coupling for easier installation, addressing the challenges of high-density packaging and field deployment in modern applications like 5G infrastructure.
