SR-021 Series High-Performance Semi-Rigid Microwave Cable

Product Overview
The SR-021 Series ultra-thin semi-rigid coaxial cable assemblies are premium high-frequency interconnect solutions from Shanghai Bing Wire & Cable built around the SR-021 ultra-fine semi-rigid cable (outer diameter only 0.535mm), these assemblies feature precision flange connectors (2.4mm or 2.92mm) to meet demanding millimeter-wave and high-frequency applications.
Designed for signal integrity and reliability in harsh environments, they support wide frequency bands up to 50GHz, making them ideal for test and measurement, aerospace, defense, and high-speed communication systems.

Key Product Features
✅ Ultra-Thin Form Factor: The 0.535mm outer diameter SR-021 cable enables high-density routing in space-constrained systems, redefining the size boundary for high-performance microwave transmission.
✅ Exceptional High-Frequency Performance:
o2.4mm version supports DC ~ 50GHz for advanced millimeter-wave test and communication applications.
o2.92mm version covers DC ~ 40GHz, fully supporting K-band and below frequency bands.
✅ Low Signal Degradation: Insertion loss ≤ 1.5dB and VSWR ≤ 1.35:1 across the full band, ensuring signal integrity and measurement accuracy.
✅ Rugged & Reliable Design: Passivated stainless steel connectors provide excellent corrosion resistance and mechanical stability. Assemblies operate reliably from -60℃ to +85℃ in extreme environments.
✅ Precision Construction: Factory-terminated SR-021 semi-rigid cable assemblies with consistent electrical and mechanical performance.
✅ Customization Available: We offer tailored solutions including custom lengths, connector types, and performance specifications to match your specific application requirements.
