What is an MMBX RF Coaxial Connector?
The MMBX RF coaxial connector is a micro-miniature bayonet-coupled RF interconnect designed for frequencies up to 12.4 GHz. It features a 50-ohm characteristic impedance, making it ideal for high-frequency signal transmission with minimal loss and reflection. Developed to meet the needs of space-constrained applications, the MMBX connector offers a compact alternative to traditional RF connectors, while maintaining military-grade reliability and excellent electrical performance.
Key Features and Specifications of MMBX Connectors
