SR-020 Miniature Microwave Cable Assemblies with MCX,SMA,BNC &PSMP Connectors

Product Description

SR‑020 miniature semi‑rigid microwave cable assemblies adopt ultra‑thin SR‑020 semi‑rigid coaxial cable as the base cable, featuring seamless copper‑tube outer conductor with 100 % shielding coverage. These pre‑terminated cable assemblies support multiple commercial RF connectors: MCX, SMA, BNC, PSMP, complying with MIL‑DTL‑17 standard specifications.

The centre conductor is silver‑plated copper‑clad steel paired with solid PTFE dielectric, delivering stable 50‑ohm impedance, outstanding shielding performance and excellent cryogenic resistant capability. The cable can be pre‑formed and fixed into static bending shapes for compact layouts inside modules and cabinets. Custom lengths and connector combinations are available upon customer requirements.

Core Advantages
