SMA Female to SMA Female Adapter, 18mm [RFS-100282]

SMA Female to SMA Female Adapter, 18mm [RFS-100282]

The SMA Female to SMA Female Adapter (18mm) is a precision barrel coupler designed to join two SMA male plugs with a defined 18mm body length standoff. This longer body length accommodates applications where standard compact barrel adapters fall short - including panel-mount installations, multi-layer PCB assemblies, rack-mounted RF chassis, and test fixtures where connector-to-connector spacing is mechanically constrained. Both ends present standard SMA female interfaces accepting SMA male plugs, and the 18mm body length ensures the two mated connectors are held at a precise, repeatable distance. This is particularly valuable in production RF test fixtures where consistent mechanical alignment is critical for repeatable measurements, and in chassis builds where an SMA port on a panel must reach an SMA port on an internal module with a specific gap between them. Constructed from gold-plated brass with PTFE dielectric, this adapter provides consistent 50 Ohm impedance and low insertion loss from DC through 18 GHz, suitable for precision RF and microwave applications.
