SMA Female to SMA Female 4-Hole Flange RF Adapter

The SMA Female to SMA Female 4-Hole Flange RF Adapter – SMA-KFK1, also known as a panel-mount SMA jack-to-jack adapter, is a precision-engineered RF component designed for stable, low-loss connections between two SMA female interfaces. With its 4-hole flange configuration, this adapter is ideal for applications requiring secure bulkhead or enclosure mounting.

Rated for frequencies up to 18 GHz and featuring a 50-ohm impedance, this SMA Female to SMA Female 4-Hole Flange RF Adapter is particularly suited for RF test benches, satellite communication assemblies, and UAV RF platforms that demand robust mechanical mounting and signal consistency.

Engineered for reliable RF performance, this SMA Jack to Jack 4-Hole Flange Adapter maintains a VSWR ≤1.15 and insertion loss ≤0.25 dB across its full operating range, enabling minimal signal reflection and transmission loss. Its straight-through design and flange structure ensure excellent repeatability in harsh or vibration-prone environments.

The SMA Female to SMA Female 4-Hole Flange RF Adapter is manufactured from passivated stainless steel for corrosion resistance and long-term durability. Its internal contacts are made from gold-plated beryllium copper to ensure low contact resistance and high electrical stability across temperature extremes ranging from -55°C to +165°C.

Fully RoHS and REACH compliant, the SMA Female to SMA Female 4-Hole Flange RF Adapter provides dependable performance for mission-critical and precision RF applications. Custom versions of this SMA in-series adapter are available on request to meet specific panel designs, mounting requirements, or interface combinations in aerospace, telecom, and test system environments.
