18 GHz Ultra-Low-Loss Precision Test RF Coaxial Cable – CFS740T

Ultra-Low-Loss 18 GHz Precision Cable for High-Power Test Systems

A 18 GHz ceiling makes CFS740T a focused option for RF calibration benches requiring ultra-low-loss precision test RF coaxial cable construction. In the CFS740T implementation at 7.60 mm, the cfs family is intended for precision test paths where attenuation, delay and bend management directly influence measurement repeatability. Its individual values distinguish the CFS740T coaxial cable within the Ultra-Low-Loss CFS Precision Test Cables range.

Fixture Layout Around a Low-Loss Test Lead — CFS740T

A 7.60 mm cable body must be planned around a 38.00 mm static bend limit and 76.00 mm dynamic bend radius, within the documented -55 to +165 °C range. On CFS740T, the FEP outer construction should be considered alongside the 7.60 mm envelope during material and routing reviews. With its substantial 7.60 mm diameter, the CFS740T RF cable is intended for layouts that can accommodate a power-focused cable envelope.

Attenuation and Power at Full Bandwidth — CFS740T

The maximum-frequency line item combines 18 GHz bandwidth, 0.725 dB/m attenuation and 0.402 kW power handling. The CFS740T core uses a 2.10 mm silver plated copper inner conductor works with a 83% velocity of propagation. Delay modelling for CFS740T can start from its documented 83% velocity-of-propagation figure.

Precision Systems Where Attenuation Must Stay Low — CFS740T

Its particular balance of bandwidth and size merits consideration in production verification and repeatable microwave measurements, especially where routing is decided early in the design. Broader geometry and performance choices are listed under Precision Test Coaxial Cables when comparing alternatives to CFS740T.
