The SMA Board Screw Fix Connector is a type of panel-mount or PCB-mount RF connector designed to securely attach to a printed circuit board using screws. It features a standard SMA interface with a threaded coupling mechanism for stable, high-frequency signal transmission—typically up to 18 GHz. The screw-fix design provides strong mechanical retention, making it suitable for applications exposed to vibration or mechanical stress. Often used in RF modules, test equipment, and communication devices, this connector ensures consistent electrical performance and robust physical stability on the board.
