Millimeter Wave Adapter 2.92/3.5-JJG (2.92MM Male to 3.5MM Male) This stainless steel-bodied adapter provides precision interconnections between 2.92mm and 3.5mm coaxial systems, engineered for high-frequency signal transmission up to 30 GHz. Featuring gold-plated beryllium copper contacts and air-gap-optimized dielectric design, it achieves ultra-low insertion loss (<0.18 dB) and VSWR <1.2:1 across DC-30 GHz bandwidths. The corrosion-resistant stainless steel construction ensures mechanical robustness and stable 50Ω impedance matching in demanding environments, including 5G mmWave testing, satellite payload integration, and radar signal analysis. MIL-STD-348 compliant for reliable performance in aerospace, defense, and lab applications. Compatible with SMA, 2.92mm, and 3.5mm connector standards.
