SMA Plug (Male) to SMA Plug (Male) Cable Assembly for MP420A Cable, DC-18 GHz VSWR 1.25

SMA Plug (Male) to SMA Plug (Male) | MP420A Coaxial Cable Assembly | 4000mm

The ROSNOL A1K50-MP420A-A1K50-4000A/18G is a long‑length 4000 mm MP420A coaxial cable assembly developed for extended signal transmission up to 18 GHz. Utilizing two SMA Plug (Male) connectors terminated via solder‑clamp assembly, the configuration supports a maximum VSWR of 1.25, minimizing mismatch losses over significant electrical lengths. The insertion loss specification ≤ 0.00186 dB/mm × L + 0.15 × Vf provides predictable and low attenuation across the full 4‑meter span.

The MP420A cable incorporates a low‑loss PTFE dielectric, precision silver‑plated conductor, and enhanced dual‑braid shielding designed for superior EMI isolation over long distances. Mechanical protection is improved via heat‑shrink tubing (HST‑W‑D6‑125C and HST‑B‑D6.4‑125C‑G), reinforcing termination points and maintaining performance under cable bending and routing stress. Length tolerance of ±1% ensures consistent electrical phase characteristics required for phased‑array systems, long‑range links, and instrumentation setups.

ROSNOL’s manufacturing processes follow ISO 9001 standards, ensuring repeatable performance and full compliance with RoHS and REACH environmental requirements. Available in standard and custom lengths, MP420A assemblies deliver reliable long‑distance RF performance with excellent mechanical endurance.
