40 GHz Compact High-Temperature Phase-Stable RF Cable IR36
P/N: IR36
– Compact cable for dense 40 GHz routing
– PI + PTFE jacket for thermal exposure
– Phase-stable path for stationary RF links
– Multilayer shielding for microwave interconnects
– Built for thermal test fixtures
Engineering Note
The IR36 / VXIR360 is a compact high-temperature phase-stable RF coaxial cable for dense 40 GHz microwave paths that must remain stationary and phase-sensitive during thermal evaluation or harsh-environment routing. Its 3.60 mm PI + PTFE jacket, LD PTFE dielectric, silver-plated copper conductor, tape shield, interlayer, and braided outer shield support compact integration where routing space is limited, while confirmed 1000 VDC dielectric withstand voltage, >90 dB shielding effectiveness, and 400 °C / 400 s high-temperature endurance keep the selection tied to thermal test fixtures, onboard RF links, and high-density aerospace cable paths.

Target Applications
Extreme Temperature Testing
Compact RF interconnects for thermal test fixtures where 40 GHz signal paths need short-term exposure capability and stable stationary routing.
High-Density Aerospace Routing
3.60 mm cable format for dense airborne or module-level paths where installation space limits cable diameter and bend radius.
High-Temperature Onboard RF Links
Stationary onboard microwave links exposed to elevated thermal stress, using PI + PTFE jacket protection and multilayer shielding.
Phase-Sensitive RF Assemblies
Harsh-environment RF assemblies where compact routing, shielding, and phase-stable cable category matter more than general-purpose flexibility.
