Series SSMP RF Coaxial Connector is an ultra-miniature, high-performance RF connecting component, designed as a smaller version of SMP connectors (about 69% the size of standard SMP). Compliant with MIL-STD-348B and GJB standards, it features a push-in blind-mate design, compact structure and ultra-wide frequency coverage, serving as a core interconnection part in high-density, high-frequency RF systems.
The series boasts superior electrical performance tailored for high-frequency scenarios. With a fixed characteristic impedance of 50Ω, it supports an ultra-wide working frequency range from DC to 65GHz (varies by model), perfectly adapting to millimeter wave, satellite communication and high-speed signal transmission needs. Key electrical parameters are excellent: VSWR is ≤1.30 for straight types and ≤1.35 for right-angle types, contact resistance of inner conductor ≤6.0mΩ and outer conductor ≤2.0mΩ, while insulation resistance ≥5000MΩ, ensuring minimal signal attenuation and distortion.
Its unique advantages lie in ultra-miniature size, blind-mate capability and flexible mating styles. The compact design enables high-density PCB layout, saving installation space, while the push-in/snap-in blind-mate design allows quick, tool-free connection without visual alignment, compensating for axial and radial misalignment. It offers full detent and smooth bore interface options, withstanding different mechanical loads for aerospace and general industrial use. Manufactured with precision processes, it adopts gold-plated beryllium copper contacts, brass housing and PTFE insulators, withstanding -55℃ to +165℃ and 100-500 plugging cycles.
Widely applied in aerospace, radar systems, satellite communication, test instruments and miniaturized high-frequency modules, it is usually paired with miniature flexible or semi-rigid cables. As high-frequency equipment evolves towards miniaturization and high density, it remains a reliable, high-performance solution for ultra-compact RF interconnection.
