SMB Cable Assemblies

Amphenol RF SMB Cable Assemblies perform from DC to 4GHz with 50Ω or 75Ω impedance. These connectors offer a snap-on interface for quick installation and ease of use. SMB assemblies are offered in a variety of configurations and are dimensioned in metric and imperial lengths. Amphenol RF SMB Cable Assemblies conform to the requirements of MIL-C-39012, and the interface is in compliance with MIL-STD-348. Typical applications are base stations, antennas, radio boards, PC/LAN, WLAN, global positioning systems (GPS), instrumentation, test and measurement laboratory equipment, and telecommunications.
