4-Hole flange SMA Female to SMA Female RF Adapter

The 4-Hole Flange SMA Female to SMA Female RF Adapter – SMA-KFK2, also referred to as a panel-mount SMA female to female adapter, is a precision coaxial component engineered for secure, low-loss interconnection between two SMA female interfaces. Its 4-hole flange configuration offers enhanced mechanical stability, making this adapter ideal for bulkhead mounting or fixed-position RF installations.

Operating up to 18 GHz with a stable 50-ohm impedance, the 4-Hole Flange SMA Female to SMA Female RF Adapter is well suited for RF test benches, satellite communication panels, and defense-grade UAV modules where vibration resistance and precise mating are essential.

This 4-Hole Flange SMA Female to SMA Female RF Adapter ensures low reflection and insertion loss, with VSWR ≤1.15 and insertion loss ≤0.25 dB. The flange design supports repeatable connections, especially in high-reliability RF setups that require secure panel integration without compromising signal quality.

Constructed from rugged passivated stainless steel, the 4-Hole Flange SMA Jack to SMA Jack RF Adapter offers exceptional resistance to corrosion and wear, even after multiple mating cycles. Its internal contacts are made from gold-plated beryllium copper, ensuring superior electrical conductivity and low contact resistance. This SMA in-series adapter performs reliably across a wide temperature range of -55°C to +165°C, meeting the demands of both lab-based and field-deployed systems.

RoHS and REACH compliant, the 4-Hole Flange SMA Female to SMA Female RF Adapter is an essential component for RF engineers working in aerospace, telecom infrastructure, and advanced test instrumentation. Custom flange cutouts or interface combinations are available upon request for integration into specialized RF assemblies.
