Product Description

SSMA Female Connector 2-Hole Flange – Precision RF Interconnect for High-Density Applications

SIPU RF Technology is proud to announce the SSMA Female Connector 2-Hole Flange (Model: SIPU-SSMA-KFB2), a micro-miniature RF coaxial solution for demanding high frequency applications. This connection is designed for operation from DC to 30 GHz with a characteristic impedance of 50Ω and has remarkable electrical performance with an insertion loss of ≤0.05√F(GHz)dB and VSWR of ≤1.05+0.012F(GHz). Fully compatible with RG405/U coaxial cable. Designed for aerospace, defence and precision test equipment, the 2-hole flange mount arrangement offers better mechanical stability and vibration resistance.

The product is constructed with gold-plated brass outer conductors and beryllium bronze core contacts, providing consistent signal integrity for over 500 mating cycles. The small footprint meets important space restrictions in current RF modules and provides strong environmental performance from -65℃ to +125℃.

What Makes SSMA Female Connectors Unique?

The SSMA series is around 70% of the normal SMA size, alleviating crucial space problems in high density RF applications. This micro-miniature interface offers outstanding electrical performance and more connections per panel space.

The 2-hole flange mount design has obvious benefits over threaded-only mounting. It distributes mechanical stress equally across the mounting surface, lowering the likelihood of signal leakage in temperature cycling or vibration environments. The large flange contact area provides a low impedance ground route, which greatly improves EMI shielding effectiveness.

Your system has the advantages of accurate port alignment and solid mechanical connection. The flange also acts as a rotating stop during mating cycles to ensure the RF performance for the life of the connection.
