SMA Female to SMA Female 4-Hole Flange RF Adapter

The SMA Female to SMA Female 4-Hole Flange RF Adapter – SMA-KFK3, also referred to as the SMA Jack to SMA Jack 4-Hole Flange Coaxial Adapter is a high-performance coaxial adapter designed to facilitate stable, low-loss connections between SMA female interfaces in both fixed and modular RF systems. Featuring a robust 4-hole flange panel mount design, this adapter offers superior mechanical stability and is ideal for embedded applications that require secure bulkhead integration.

Operating up to 26.5 GHz with a characteristic impedance of 50 ohms, the SMA Female to SMA Female 4-Hole Flange RF Adapter ensures reliable performance in a broad range of RF environments. This SMA female to female adapter is especially suited for aerospace and defense systems, vehicular communication platforms, and RF test benches, where vibration resistance and repeatable signal performance are critical.

The 4-Hole Flange SMA Female to Female Adapter achieves excellent electrical characteristics with a typical VSWR ≤1.1 and insertion loss ≤0.25 dB across its operating bandwidth. The flange-mount construction ensures secure and repeatable connections during extended test cycles or in mobile installations subject to environmental stress.

Built from corrosion-resistant passivated stainless steel with gold-plated beryllium copper contacts, the SMA Female to SMA Female 4-Hole Flange RF Adapter delivers mechanical durability and electrical stability across an operating temperature range of -55°C to +165°C. Its robust build allows for frequent mating cycles and exposure to harsh testing conditions.

Fully compliant with RoHS and REACH directives, the SMA Female to SMA Female 4-Hole Flange RF Adapter is an excellent choice for engineers designing rugged RF systems or integrating panel-mounted SMA interfaces in precision assemblies. Custom flange patterns or connector variants are available upon request for specialized configurations in telecommunications, satellite payloads, and radar subsystems.
