Millimeter Wave Adapter 2.92/3.5-KKG (2.92MM Female to 3.5MM Female) This high-frequency dual-port interface adapter enables seamless transitions between 2.92mm and 3.5mm coaxial systems, engineered for precision signal transmission up to 30 GHz. Featuring gold-plated beryllium copper contacts and PTFE dielectric insulation, it achieves ultra-low insertion loss (<0.15 dB) and VSWR <1.25:1 across DC-30 GHz bandwidths. The stainless steel housing with precision-machined threads ensures mechanical durability and stable impedance matching (50Ω) in millimeter-wave applications, including 5G NR testing, satellite communications, and phased-array radar calibration. MIL-STD-348 compliant for rugged use in lab, field, and aerospace environments. Compatible with SMA, 2.92mm, and 3.5mm connector series.
