Product Overview

YILIANDUO is a precision in-series 3.5mm millimeter-wave coaxial adapter engineered for full-frequency microwave testing ranging from DC to 34GHz. Constructed with anti-corrosion passivated stainless steel shell and gold-plated beryllium copper inner contact, this 3.5-series connector shares unified outer dimension to achieve mechanical interconnection with standard SMA and 2.92mm(K-type) RF connectors, resolving hybrid test bench conversion demands between three mainstream high-frequency connector specs.

Available in three gender options: Female to Female / Male to Female / Male to Male, this adapter serves dual-market demands: B2B bulk procurement for RF component distributors, aerospace factories, automotive radar manufacturers and global 5G communication enterprises, plus B2C university lab researchers, R&D engineers and RF DIY enthusiasts for VNA calibration and high-frequency circuit debugging. It is a cost-effective replacement for expensive imported adapters from Fairview, Pasternack and Mini-Circuits.

Features

✅ 3 Standard Gender Variants Available: FF / MF / MM
Three common in-series combinations to cover most lab interconnection requirements; flexible option selection for custom RF fixture assembly.

✅ Universal Mechanical Compatibility: 3.5mm ↔ SMA ↔ 2.92mm
Same outer diameter design enables direct plug-and-play between 3.5mm, standard SMA and 2.92mm(K-type) without mechanical damage; supports mixed-series test system setup.

✅ Premium Passivated Stainless Steel Construction
Whole housing with stainless steel passivation treatment to eliminate free iron & prevent secondary oxidation corrosion, extend service life under damp lab and fluctuating industrial temperature; gold-plated beryllium copper pin offers superior wear resistance over hundreds of mating cycles.

✅ Ultra-Stable Electrical Performance (DC~34GHz Full Band)
  • Standard 50Ω industry impedance for millimeter-wave RF circuits
  • Max VSWR ≤1.2 across full DC-34GHz spectrum
  • Ultra-low insertion loss ≤0.05dB to minimize high-frequency signal attenuation & waveform distortion

✅ Full EMI Shielding & Strict Millimeter-Wave Spec

Integrated all-metal shielding shell restrains electromagnetic interference; exclusively designed for DC-34GHz high-frequency millimeter/microwave use, not applicable for low-frequency circuits below 1GHz.

Important Usage Notes

  • This precision millimeter-wave adapter is designed only for DC-34GHz high-frequency testing; avoid low-frequency wiring below 1GHz.
  • Control screwing torque moderately during installation; excessive force will deform inner gold-plated pin and damage electrical indicators.
  • Store in dry, dustproof environment to protect precision gold plating against moisture rust.

FAQ

Q1: Can this 3.5mm adapter connect directly with SMA or 2.92mm connectors?

A: Yes, the unified outer diameter supports mechanical interconnection between 3.5mm, SMA and 2.92mm series without hardware damage.

Q2: Does the adapter keep stable VSWR performance across full DC~34GHz?

A: Yes, precision CNC machining ensures VSWR ≤1.2 and ≤0.05dB insertion loss within entire DC-34GHz working range.

Q3: Do you provide bulk pricing for lab & enterprise bulk orders?

A: Volume discount available for orders over 50pcs; contact our sales team for customized wholesale quotation.

Q4: What’s the benefit of passivated stainless steel housing?

A: Passivation eliminates free iron on stainless steel surface to avoid oxidation & rust, stable service performance in humid lab and harsh industrial environments.
