Product Overview

YILIANDUO is a precision air-dielectric cross-series millimeter-wave adapter engineered for signal conversion between 1.85mm(V-type) female and standard 2.4mm male RF interfaces, stably rated for continuous DC~50GHz full-band operation. Built with passivated anti-corrosion stainless steel housing and gold-plated beryllium copper inner contact, this professional interconnect solves conversion challenges between 1.85mm max 67GHz ultra-high-frequency test gear and mainstream 2.4mm 50GHz millimeter-wave modules, exclusively mechanically compatible with 1.85 & 2.4mm series only (not mateable with SMA/3.5mm/K-type 2.92mm).

This premium RF component targets dual-market demand: B2B bulk sourcing for global RF distributors, aerospace defense factories, automotive millimeter radar manufacturers and 5G mmWave R&D enterprises, plus B2C university high-frequency lab researchers, measurement engineers and RF DIY specialists for VNA calibration & custom test fixture assembly. It’s a cost-effective drop-in replacement for high-cost imported adapters from Fairview, SV Microwave and TE Connectivity.

Features

✅ Exclusive Cross Transition:1.85mm(V) Female ↔2.4mm Male | Only 1.85/2.4 Interoperable
Industry-standard air interface design; mechanically mates directly between 1.85mm(V) and 2.4mm without hardware damage, incompatible with SMA/3.5/2.92(K) to avoid mismatched connector damage, standardized for professional high-frequency lab setup.

✅ Premium Passivated Stainless Steel & Wide Temperature Resistance
Full stainless steel housing with chemical passivation removes free iron to eliminate secondary rust/oxidation; stable mechanical performance across -55℃ ~ +165℃ extreme ambient for airborne, outdoor and variable-temperature industrial testing; gold-plated inner pin boosts wear for hundreds of repeated mating cycles.

✅ Excellent DC~50GHz Full-Band Electrical Specs
  • Standard industry 50Ω characteristic impedance for all millimeter-wave RF circuits
  • Max VSWR ≤1.25 across full DC-50GHz working spectrum
  • Ultra-low max insertion loss ≤0.05dB to minimize high-frequency signal attenuation & waveform distortion
✅ Air-Dielectric Precision Structure for Millimeter Wave
Both 1.85(V) &2.4mm adopt air-spaced inner insulation instead of solid dielectric, drastically cut parasitic high-frequency loss, far superior to conventional low-frequency SMA connectors limited below 18GHz.

✅ All-Metal Closed EMI Shielding
Integrated full-metal shielding shell suppress external electromagnetic interference, keep steady signal integrity under high-vibration radar & aerospace testing; exclusively for ≥30GHz millimeter-wave, unsuitable for below-1GHz low-frequency wiring.

FAQ

Q1: Can this adapter connect to SMA or 3.5mm connectors?

A: No, 1.85 &2.4mm only mechanically compatible with each other, cannot mate with SMA/3.5/2.92mm to prevent connector damage.

Q2: Can the 1.85 side do temporary testing up to 67GHz?

A: 1.85(V-type) structural max 67GHz; continuous long-term working should stay within rated DC~50GHz.

Q3: Is bulk discount available for lab/enterprise big orders?

A: Volume preferential pricing for orders over 50pcs; contact sales team for customized wholesale quotation.

Q4: What’s passivated stainless steel advantage?

A: Passivation removes free iron to stop rust & oxidation, stable performance under wide-range fluctuating temperature environment.
