The SMA female to SMA female 4 Holes Flange RF Coaxial Adapter is built for engineers and technicians who need a robust, repeatable connection point in RF systems. By combining a standard SMA female interface on both sides with a rigid 4-hole flange, it allows you to bring an SMA feedthrough cleanly through a panel, bulkhead, or enclosure while maintaining excellent electrical integrity. Designed around a 50 Ω characteristic impedance, this adapter is suitable for a wide range of RF and microwave applications, from lab test benches to embedded communication modules and RF control boards. Depending on the specific build, similar 4-hole SMA flange adapters are commonly rated from DC up to 18 GHz or higher, ensuring consistent performance over broad bandwidths and supporting modern high-frequency systems. The precision-machined body ensures good VSWR and low insertion loss when properly installed with compatible SMA connectors. Mechanically, the 4-hole flange provides a secure mounting surface that resists vibration, cable strain, and repeated mating cycles. This makes it an excellent choice for environments where connections must stay put—inside rack systems, RF drawers, outdoor units, or mobile platforms. The flange holes are typically arranged on a standard pattern for easy integration into custom metalwork or pre-cut panels. This adapter is ideal for interconnecting coaxial components, extending SMA runs through walls or chassis, or creating fixed reference ports on instruments and fixtures. Whether you are building prototypes or maintaining production systems, it offers a convenient way to achieve a clean, professional installation without sacrificing RF performance. With its compact size, standard SMA compatibility, and durable construction, the SMA female to SMA female 4 Holes Flange RF Coaxial Adapter is a dependable building block for RF signal routing, measurement setups, and long-term deployed installations.
