SMA Adapters are precision RF interconnect components used to join, convert, or extend SMA connectors in coaxial systems. They enable reliable signal transmission up to 18 GHz (and higher in precision types) with low VSWR and minimal insertion loss. SMA adapters are commonly used to change gender, polarity, or orientation (straight, right-angle, bulkhead) and are widely applied in telecom, RF testing, antennas, microwave systems, and instrumentation.
