Series 2.92 RF Coaxial Connector, also known as K-band connector, is a high-performance precision RF connecting component developed based on SMA connectors, featuring air dielectric design, compact structure and broad frequency coverage. Compliant with GJB and MIL standards, it is widely recognized for excellent electrical and mechanical stability, serving as a core interconnection part in millimeter wave systems, bridging the gap between conventional RF and high-frequency millimeter wave applications.
The series boasts outstanding performance tailored for high-frequency scenarios. With a fixed characteristic impedance of 50Ω, it supports a wide working frequency range from DC to 40GHz (up to 46.5GHz for enhanced models), perfectly adapting to 5G millimeter wave and satellite communication needs. Key electrical parameters are superior: insertion loss is as low as 0.04×√f (GHz) dB, VSWR is controlled within ≤1.2:1, contact resistance of inner conductor ≤3mΩ and outer conductor ≤2mΩ, ensuring minimal signal attenuation and distortion.
A unique advantage is its compatibility with SMA and 3.5mm connectors, enabling seamless mating with existing equipment while extending frequency performance, greatly improving system flexibility. Manufactured with precision processes, it uses beryllium copper inner contacts (gold-plated) and stainless steel or brass outer housing, with polyetherimide insulation, enhancing conductivity and corrosion resistance. It withstands -55℃ to +125℃ working temperature, 500+ plugging cycles, and harsh conditions like vibration and salt fog.
Its application scenarios cover satellite communication, missile 制导，radar engineering, test instruments, 5G millimeter wave base stations and aerospace equipment. As high-frequency communication develops, it remains a reliable, cost-effective solution for high-performance RF interconnection, empowering the advancement of millimeter wave technologies.
