If an RF connector (Radio Frequency connector), also known as a Coax Connector changes the impedance of its transmission wire, reflections and losses will occur. RF connectors must block external signals from reaching the circuit, as well as prevent leakage of energy out of the circuit. Common types of RF Connectors include SMA, SMB, SSMB, SMC, MCX, MMCX, MC CARD, BNC, TNC, UHF, MINI-UHF, and microminiature IPX interfaces. Below is a list of RF connector suppliers.
