BMA RF Connectors for Semi-flexible & Semi-rigid Cable are designed for high-frequency RF interconnection systems that require compact structure, reliable electrical performance, and stable mechanical connection. These connectors are commonly used with semi-flexible cables such as .086" (RG402) and semi-rigid cables such as .047" (RG405), providing a secure transition between cable conductors and RF modules while maintaining shielding effectiveness and signal integrity.
The main function of BMA RF Connectors for Semi-flexible & Semi-rigid Cable is to establish fixed RF links inside electronic modules, microwave assemblies, and communication equipment. By integrating with the cable's metallic outer conductor through precision assembly processes, these connectors help reduce signal leakage, minimize electromagnetic interference, and support stable operation in high-frequency environments.
