High-Performance RF & Microwave Cable Assemblies (DC to 110 GHz)
Engineered for high-frequency laboratory testing, automated test equipment (ATE), vector network analyzer (VNA) interconnects, and demanding aerospace/defense systems, our comprehensive portfolio of RF Cable Assemblies delivers ultra-low insertion loss, exceptional phase stability, and superior durability from DC up to 110 GHz.
Covering critical frequency tiers including 18 GHz, 26.5 GHz, 40 GHz, 50 GHz, 67 GHz, and 110 GHz, our cable assemblies are meticulously crafted to withstand rigorous mechanical flexing while maintaining pristine signal integrity. We offer an extensive selection of precision coaxial interfaces, featuring SMA, N-Type, SMP, 3.5mm, 2.92mm (K), 2.4mm, 1.85mm (V), and 1.0mm connectors. Utilizing ultra-stable low-density PTFE dielectrics, spiraled flat-wire shielding, and armored stainless steel outer jackets, our cables provide outstanding resistance to crushing, torque, and environmental wear.

Frequently Asked Questions (FAQ)
What is the difference between armored and flexible test cables? Armored test cables feature a robust stainless steel outer coil or sleeve that prevents crushing, kinking, and over-bending, making them ideal for busy R&D labs and production floors. Flexible cables offer higher physical flexibility for tight routing inside instrument enclosures.
How do I select the right connector for mmWave cables (above 40 GHz)? For frequencies above 40 GHz, intermateability and precision are critical. We recommend 2.92mm (up to 40 GHz), 2.4mm (up to 50 GHz), 1.85mm (up to 67 GHz), and 1.0mm (up to 110 GHz). Note that 2.92mm is fully intermateable with SMA and 3.5mm connectors.
Can you provide custom phase-matched cable sets? Yes! We offer custom service for multi-port receiver systems, antenna arrays, and differential measurement setups.
