SMB Connectors & Adapters

Amphenol RF SMB Connectors and Adapters offer broadband capability through 4GHz with a snap-on connector design. The SMB PCB slide-on plug and jack allows board-to-board mounting with a low insertion force. The quick connect/disconnect snap-on mating reduces installation time. The connectors are MIL-C-39012 compliant, while the interface is MIL-STD-348 compliant. Amphenol RF SMB Connectors and Adapters are available in 50Ω and 75Ω impedances. Typical applications include base stations, antennas, radio boards, instrumentation, telecom, and more.
