SMA Male to SMA Male High-Performance RF Test & Measurement Cable Assembly – Use CFT240H18 Coax

SMA Male to SMA Male High-Performance RF Test & Measurement Cable Assembly – Built with CFT240H18 Coaxial Cable

The SMA Male to SMA Male High-Performance RF Test & Measurement Cable Assembly — model TCDN-SMSM-1M — is a versatile, general-purpose RF test cable designed for dependable operation up to 18 GHz. This 1 meter assembly is constructed using Mechanc’s CFT240H18 coaxial cable, a phase-stable enhancement of the CFT240 Phase-Stable 67 GHz Precision Test Coaxial Cable with FEP Jacket. Both ends are terminated with precision SMA male connectors (reference SMA-JCFT240H18-1), providing a compact and reliable interconnect for SMA-based RF instruments and fixtures.

Accurate RF Performance up to 18 GHz

Designed as a regular high-quality test cable, the TCDN-SMSM-1M supports a continuous DC–18 GHz operating band, delivering the impedance stability needed for everyday RF and microwave measurements. The assembly offers a 1.15 typical VSWR and a 3.12 dB typical insertion loss over a 1 meter length, enabling clean signal paths for VNA sweeps, S-parameter checks, gain and return-loss measurements, and general-purpose bench testing in development or production environments.

Phase-Stable CFT240H18 Construction for Repeatable Measurements

The CFT240H18 coaxial cable is engineered to limit electrical drift as the cable is repositioned, bent, or exposed to temperature changes. With ±6° mechanical phase stability and ±0.06 dB amplitude stability, it supports repeatable results over many measurement cycles. Its slim 2.4 mm outer diameter and 24 mm minimum bend radius make it easy to route in dense setups, while a typical 2,000-cycle bend life and an 81% velocity of propagation help maintain long-term reliability and accurate time-domain behavior across a wide –55 °C to +165 °C operating range.

Precision SMA Interfaces for Everyday RF Test Benches

Each end of the TCDN-SMSM-1M features precision SMA-JCFT240H18-1 male connectors designed for low reflection and consistent mating with common RF test equipment. These SMA interfaces are well-suited for connecting to network analyzers, signal generators, spectrum analyzers, and modular RF platforms where repeatable performance and compact form factor are required.
