Siretta Ultra Band Cables
Siretta Ultra Band Cables – SHC300 are high-performance assemblies engineered for demanding high-frequency and broadband applications. Supporting operation up to 40 GHz with 2.92 mm connectors, they deliver low insertion loss, excellent phase stability, and exceptional shielding effectiveness, ensuring consistent signal integrity across the full frequency range. Each assembly is built using premium materials and precision SMA or 2.92 mm connectors to provide superior electrical and mechanical reliability. The SMA versions operate up to 26.5 GHz, while the 2.92 mm variants extend capability to 40 GHz, meeting the needs of modern high-bandwidth and K-band systems. The cable utilizes flame-retardant materials tested in accordance with IEC 60695-11-10:2013 Method B, providing enhanced fire safety while maintaining the outstanding electrical performance required for demanding RF and microwave applications. Whether connecting a VNA to a device under test, linking components in a high-frequency test bench, or integrating advanced RF modules, SHC300 cables ensure accurate, repeatable, and stable performance in every application.
