Series SSMB RF Coaxial Connector is a micro-miniature, high-performance RF connecting component, designed as a compact version of the SMB connector. Compliant with IEC 169-19 and MIL-STD-202 standards, it features a convenient snap-on locking mechanism, small size and reliable performance, serving as a core interconnection part in space-constrained, high-density RF systems.
The series boasts excellent electrical performance tailored for diverse scenarios. With a standard characteristic impedance of 50Ω (75Ω optional for specific applications), it supports a working frequency range of DC to 3GHz (up to 12.4GHz for enhanced models), perfectly adapting to low-to-high frequency signal transmission needs. Key electrical parameters are reliable: VSWR is ≤1.35 for straight types and ≤1.63 for right-angle types, contact resistance of inner conductor ≤5mΩ and outer conductor ≤2.5mΩ, insulation resistance ≥1000MΩ, ensuring minimal signal attenuation and distortion.
Its unique advantages lie in the snap-on coupling design and ultra-compact size, enabling quick, tool-free mating and dense PCB layout to save space—ideal for handheld and miniaturized devices. Manufactured with precision processes, it adopts brass housing (gold or nickel-plated), gold-plated beryllium copper female contacts and brass male contacts, paired with PTFE insulators, enhancing conductivity and corrosion resistance. It can withstand -55℃ to +155℃ working temperature, 500+ plugging cycles, and harsh conditions like vibration and salt fog.
Widely applied in handheld radios, test instruments, micro radio equipment, satellite communication modules and high-density PCB interconnections, it is usually paired with miniature flexible or semi-rigid cables. As equipment evolves towards miniaturization and high efficiency, it remains a cost-effective, reliable solution for micro-miniature RF interconnection, supporting stable signal transmission in compact systems.
