Product Overview

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.

This cross-type component targets dual-market needs: B2B bulk procurement for global RF distributors, aerospace manufacturers, automotive radar factories and 5G millimeter-wave enterprises, plus B2C university RF lab researchers, hardware R&D engineers and measurement DIY users for VNA calibration and custom test fixture assembly. It serves as a cost-effective replacement for high-priced imported adapters from Fairview, Pasternack and other international RF brands.

Features

✅ 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.

Important Usage Notes

  • This precision millimeter-wave adapter is designed exclusively for DC~34GHz high-frequency testing, not applicable for conventional low-frequency circuits below 1GHz.
  • Fasten 2.92/3.5 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 2.92-3.5 adapter connect directly with regular SMA connectors?

A: Yes, unified outer diameter enables mechanical interconnection among 2.92mm,3.5mm and SMA without mechanical damage.

Q2: Does the product keep stable VSWR performance under full DC~34GHz continuous operation?

A: Precision CNC machining ensures VSWR ≤1.25 and ≤0.1dB insertion loss across full DC~34GHz frequency band.

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

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

Q4: What is the advantage of passivated stainless steel housing?

A: Passivation removes free iron on steel surface to avoid oxidation & rust, stable service performance under wide -55~+165℃ temperature fluctuation.
