RF Connector Overview

Function: Connects RF (Radio Frequency) signals in high-frequency applications.

Common Types:

• SMA – Up to 18 GHz, common in Wi-Fi, test equipment
• SMB – Snap-on, up to 4 GHz, used in telecom
• SMC – Threaded SMB variant
• N-Type – Up to 11 GHz, robust, outdoor use
• BNC – Up to 4 GHz, quick connect/disconnect
• U.FL (IPX) – Ultra-miniature, internal PCB use (e.g., GPS, cellular modules)

Key Parameters: Impedance (usually 50Ω), frequency range, coupling type, VSWR, insertion loss.

Applications: Antennas, RF modules, radar, wireless comms, test & measurement.
