Product Overview

YILIANDUO is a premium cross-series millimeter-wave coaxial adapter designed for signal conversion between high-frequency 2.4mm and 3.5mm connector interfaces, rated for continuous DC~34GHz operation with peak test performance up to DC-50GHz. Built with passivated anti-corrosion stainless steel housing and gold-plated beryllium copper inner pin, this air-dielectric threaded interconnect resolves hybrid test setup demands between 2.4mm ultra-high-frequency VNA equipment and mainstream 3.5mm/SMA test cables.

This cross-type connector covers dual-market positioning: B2B bulk sourcing for global RF distributors, aerospace manufacturers, automotive radar factories and 5G mmWave communication enterprises, plus B2C university RF lab researchers, hardware R&D engineers and measurement DIYers for VNA calibration and custom test fixture assembly. It is an economical replacement for high-cost imported adapters from Fairview, Pasternack and Amphenol.

Features

✅ Cross-Series Transition: 2.4mm Female ↔3.5mm Female | Standard SMA Mechanical Compatibility
2.4mm is ultra-high-frequency air interface design supporting max 50GHz; unified outer dimension enables mechanical interconnection between 3.5mm and regular SMA connectors without hardware damage, perfect for mixed-spec lab test bench construction.

✅ Premium Passivated Stainless Steel Construction
Full stainless steel body with professional passivation treatment eliminates free iron to avoid secondary oxidation and rust, extending service life under humid lab & variable-temperature industrial working conditions; gold-plated beryllium copper contact delivers outstanding wear resistance after hundreds of repeated mating cycles.

✅ Top-Tier Full-Band Electrical Specs (Rated DC~34GHz, Max Test DC~50GHz)
  • Standard industry 50Ω characteristic impedance for all millimeter-wave RF circuits
  • Max VSWR ≤1.25 across full DC-34GHz working spectrum
  • Ultra-low max insertion loss ≤0.05dB to minimize high-frequency signal attenuation & waveform distortion

✅ Advanced Air-Dielectric 2.4mm Connector Structure

2.4mm series features air-spaced threaded design, compact size & lightweight, engineered exclusively for ultra-wideband millimeter-wave measurement, distinct from conventional low-frequency SMA adapters limited below 18GHz.

✅ Full Closed Metal EMI Shielding

Integrated all-metal shielding shell suppresses external electromagnetic interference, ensures stable signal integrity under high-interference industrial & airborne testing environments; only for high-frequency mmWave instead of low-frequency wiring below 1GHz.

Important Usage Notes

  • This precision millimeter-wave adapter is designed exclusively for DC~50GHz high-frequency testing, not applicable for conventional low-frequency circuits below 1GHz.
  • Tighten threaded ports with moderate torque; over-tightening will deform inner gold-plated pin and damage original electrical performance.
  • Store in dry, dustproof storage space to protect precision gold plating against moisture corrosion.

FAQ

Q1: Can this 2.4-3.5 adapter connect directly with standard SMA connectors?

A: Yes, unified outer diameter enables mechanical interconnection between 3.5mm and regular SMA without mechanical damage.

Q2: What’s the difference between rated 34GHz and max test 50GHz?

A: Stable continuous operation under DC~34GHz; structural design supports short-term peak test up to DC-50GHz for ultra-high-frequency verification.

Q3: Is volume discount available for enterprise/lab bulk purchase?

A: Preferential bulk pricing available for orders over 50pcs; contact sales team for customized wholesale quotation.

Q4: What is passivated stainless steel’s core advantage?

A: Passivation removes free iron on steel surface to avoid oxidation & rust, stable service performance under long-term variable-temperature lab and industrial environments.
