SMA connectors are precision subminiature connectors primarily used for higher frequencies with excellent electrical performance from DC through 18 GHz. SMA connectors are primarily used where trends toward higher frequencies, miniaturization, and SMA connectors are built in accordance with MIL-C-39012 and are available for a variety of flexible and semi-rigid cables. Brass SMA connectors provide a cost effective solution for applications where stainless steel construction is not required.

Application:
Base Station, Instrumentation, Measurement System, Microwave Component, PC/LAN, Process Control, Telecommunication, Wireless
