Product details

GLRG179 is the 75 Ω choice in this coaxial-cable range. Confirm that impedance with the equipment and connector system before selecting it for an assembly; it should not be treated as an interchangeable replacement for a 50 Ω cable. The 2.54 ± 0.1 mm jacket diameter is also relevant to connector termination and routing space.

The DC–3 GHz VSWR specification and the 11 GHz cutoff entry describe different limits. Use the former for the stated matching performance and request insertion-loss data for the proposed frequency and cable length. The PTFE dielectric and FEP jacket support the listed temperature range, but the connectors, termination process and complete assembly need their own temperature and mechanical checks.
