YILIANDUO is a professional cross-series millimeter-wave RF interconnect designed to convert between 2.92mm(K-type) female and 3.5mm female ports, fully electrically validated for DC~34GHz full-spectrum high-frequency measurement. Built with passivated anti-rust stainless steel housing and gold-plated beryllium copper inner contact, this adapter leverages unified outer dimension design to realize mechanical interconnection among 2.92mm(K-type), 3.5mm and regular SMA connectors, solving hybrid test system conversion demands between three mainstream high-frequency RF specs.
✅ Cross-Series Transition: 2.92mm(K) Female ↔3.5mm Female | Triple Compatibility with SMA
Unified outer diameter enables direct mechanical mating of 2.92mm,3.5mm and standard SMA connectors without hardware damage; ideal for building mixed-spec test benches connecting K-type VNA equipment, 3.5mm test cables and conventional SMA RF modules.
✅
Premium Passivated Stainless Steel & Wide Temperature Endurance
Full stainless steel housing with chemical passivation treatment eliminates free iron to avoid secondary oxidation and rust; stable mechanical performance across -55℃ ~ +165℃ extreme temperature range, fit for outdoor airborne and high-low temp industrial test environments.
✅
Excellent Full-Band Electrical Performance DC~34GHz
- Standard industry 50Ω characteristic impedance for all millimeter-wave RF circuits
- Max VSWR ≤1.25 across entire DC-34GHz working spectrum
- Ultra-low max insertion loss ≤0.1dB to minimize high-frequency signal attenuation & waveform distortion
- Gold-plated beryllium copper center pin boosts wear resistance for hundreds of repeated plugging cycles
✅ Full Metal Integrated EMI Shielding
Closed all-metal shielding shell suppresses external electromagnetic interference, keeps consistent signal integrity under complex vibration & high-interference test surroundings; exclusively engineered for high-frequency millimeter-wave instead of low-frequency wiring below 1GHz.
