Description
2.92mm Jack (Female) to 2.92mm Jack (Female) Adapter | Straight Bullet Design | Screw-Lock | Stainless Steel Body
The ROSNOL AD-K2K25A-BL25/9X-9X is a straight bullet adapter engineered for high-frequency RF performance. It supports DC to 40 GHz with 50 Ω impedance, VSWR ≤ 1.25 (≥ 19.08 dB return loss), and insertion loss ≤ 0.04 × √F (GHz) dB. Electrical integrity includes insulation resistance ≥ 5 GΩ, test voltage 750 V rms, working voltage 250 V rms, and RF leakage ≥ 100 dB up to 1 GHz. The screw-lock coupling ensures secure engagement and mechanical durability for ≥ 500 mating cycles, with recommended torque 0.80–1.10 Nm and test torque ≤ 1.70 Nm.
Materials and plating are optimized for reliability: centre contact in beryllium copper with gold plating over non-magnetic nickel-phosphorus underplating; body in stainless steel passivated; insulator in PEI; gasket in silicone rubber; coupling nut in stainless steel passivated. The adapter offers corrosion resistance and operates across a temperature range of -40°C to +125°C.
ROSNOL’s precision-engineered RF adapters deliver reliable performance across a wide range of RF and microwave systems. Manufactured under ISO 9001-certified processes, all products are fully compliant with RoHS and REACH regulations. Offering high quality at competitive pricing, ROSNOL adapters serve as cost-effective alternatives to leading European and American brands, with customization available for materials, plating, and mechanical design.
