18 GHz Semi-Rigid Cryogenic RF Coaxial Cable – CRT020

Subminiature 18 GHz Cryogenic Semi-Rigid Cable for Ultra-Cold Instruments

The CRT020 specification targets quantum research platforms, pairing cryogenic semi-rigid RF coaxial cable construction with a 18 GHz bandwidth. In the CRT020 implementation at 0.58 mm, the crt conductor system is specified down to -268 °c for signal routing into cryogenic stages where ordinary cable materials are unsuitable. Its individual values distinguish the CRT020 coaxial cable within the Cryogenic Semi-Rigid Coaxial Cables range.

Subminiature Routing into Cryogenic Stages — CRT020

The cable occupies a 0.58 mm envelope and calls for at least 2.90 mm static bend radius while operating across -268 to +150 °C. For CRT020, routing decisions should remain within the documented bend geometry rather than relying on a generic family assumption. At only 0.58 mm in diameter, the CRT020 RF cable is the miniature-format option for tightly packed RF layouts.

Cryogenic Signal-Transfer Fundamentals — CRT020

The maximum-frequency line item combines 18 GHz bandwidth, 23.902 dB/m attenuation and 0.015 kW power handling. The CRT020 core uses a 0.13 mm silver plated copper-nickel alloy inner conductor works with a 70% velocity of propagation. Delay modelling for CRT020 can start from its documented 70% velocity-of-propagation figure.

Ultra-Cold Measurement and Detector Connections — CRT020

Its particular balance of bandwidth and size merits consideration in low-temperature detectors and superconducting experiments, especially where routing is decided early in the design. Broader geometry and performance choices are listed under Semi-Rigid Coaxial Cables when comparing alternatives to CRT020.

For engineering teams comparing real specification limits, CRT020 adds a clearly differentiated option to the Mechanc cable portfolio. The Mechanc Shanghai Information Technology Co., Ltd. portfolio provides the wider context for CRT020 and its intended RF role.
