YILIANDUO is an in-series precision 2.4mm male female RF coaxial adapter engineered for full-band millimeter wave testing from DC up to 50GHz. Constructed with anti-corrosion passivated stainless steel housing and gold-plated beryllium copper inner contact, this high-frequency interconnect delivers ultra-low insertion loss and tight impedance matching, supporting direct interconnection with standard 1.85mm millimeter-wave connectors.
✅ In-Series 2.4mm Female to Female Interface | Cross-Compatible with 1.85mm Connector
Standard air-dielectric threaded 2.4mm millimeter-wave design, reliably mates with all industry-standard 2.4mm & 1.85mm series RF plugs; different from conventional bulky SMA connectors, compact lightweight structure saves installation space for dense test fixtures.
✅
Premium Passivated Stainless Steel Construction
Whole body adopts stainless steel with electrochemical passivation treatment to block secondary oxidation and rust, extending service life under long-term damp lab and industrial operating environments; gold-plated inner pin improves conductivity and anti-abrasion for hundreds of repeated plug cycles.
✅
Excellent Full-Band Electrical Performance (DC~50GHz)
- Standard 50Ω nominal impedance, industry benchmark for millimeter-wave RF circuits
- Max VSWR ≤1.3 across entire DC-50GHz frequency spectrum
- Ultra-low Insertion Loss ≤0.05dB to avoid high-frequency signal attenuation & distortion
✅ Robust EMI Shielding for Signal Integrity
Integrated full shielding shell suppresses electromagnetic interference (EMI), keeps stable signal output under complex industrial test environment, ideal for sensitive mmWave measurement projects.
✅ Exclusive for Millimeter-Wave Applicatio
Specially calibrated for high-frequency microwave/mmWave; not recommended for low-frequency circuits below 1GHz, consistent with global RF lab industry specification.
