18 GHz Semi-Rigid High-Temperature Ultra-Low-Loss RF Coaxial Cable – CRM141DS

High-Power 18 GHz Semi-Rigid Cable with Ultra-Low-Loss Performance

CRM141DS brings a 18 GHz operating range to stable microwave distribution in a high-temperature ultra-low-loss semi-rigid RF coaxial cable format. In the CRM141DS implementation at 3.58 mm, the crm geometry combines high-temperature capability with a higher propagation factor, supporting efficient fixed paths in demanding microwave assemblies. Its individual values distinguish the CRM141DS coaxial cable within the Phase-Stable Semi-Rigid Coaxial Cables range.

Efficient Power Transfer in Fixed Microwave Paths — CRM141DS

The result is a credible candidate for low-loss radar paths and high-temperature RF modules when the stated electrical and bending limits match the assembly brief. Broader geometry and performance choices are listed under Semi-Rigid Coaxial Cables when comparing alternatives to CRM141DS.

Efficient RF Transfer at Rated Bandwidth — CRM141DS

Its band-edge figures are 1.369 dB/m and 0.253 kW at 18 GHz, giving a direct basis for path budgeting. The CRM141DS core uses a 1.05 mm silver plated copper inner conductor works with a 81% velocity of propagation. Delay modelling for CRM141DS can start from its documented 81% velocity-of-propagation figure.

Mechanical Fit for Efficient High-Power Transfer — CRM141DS

Mechanical layout begins with a 3.58 mm profile, a 13.50 mm static bending requirement, and the stated -55 to +250 °C operating window. For CRM141DS, routing decisions should remain within the documented bend geometry rather than relying on a generic family assumption. Its 3.58 mm profile gives the CRM141DS RF cable a middle-ground geometry between miniature routing and larger power-oriented cables.

Selection of CRM141DS can therefore be based on its recorded performance and geometry, not simply on the surrounding cable family. The Mechanc Shanghai Information Technology Co., Ltd. portfolio provides the wider context for CRM141DS and its intended RF role.
