AtlanTecRF, a leading global RF and microwave components and equipment manufacturer, announced the latest addition to its stable of high performance cable assemblies - the ACH series of high velocity products available in frequency ranges of DC-18, DC-26.5, DC-40 and DC-50 GHz.

With velocity of propagation of 83%, the standard assemblies are available from stock  in lengths of 0.5, 1.0, 1.5 and 2.0 metres although custom assemblies can also be delivered to suit specific equipment applications. Overall cable O/D ranges from 7.8mm for the 18GHz designs to 3.6mm for the 40GHz and 50GHz versions.

All series have an operating temperature range of -55 to +165C and installation bend radii are down to 18mm, making them very suitable for use in challenging applications, military and commercial, as well for general purpose test and laboratory use.

Phase stability is a key feature at just +/-5 degrees under mechanical handling and 500 ppm over the -55+125C temperature range.

“This new series of high velocity and low loss cables represents another step forward in our interconnect technology offering. We always seek to provide the very best in value and performance and the ACH series do just that” said AtlanTecRF C.E.O. at the product announcement and launch.

In terms of insertion loss an 18GHz, 0.5 metre assembly exhibits only 0.4dB at the top of its frequency range while the 40GHz version has a worst case VSWR of 1.2:1.

Power handling starts at 75 watts maximum for the ACH-CA40 and ACH-CA50 products at 40GHz to over 700 watts for the ACH-CA18 cable at 6GHz. All connectors are stainless steel, SMA male up to 26.5GHz, 2.92mm to 40GHz and 2.4mm to 50GHz.

Cable weight is kept low with the 18GHz weighing in at 130g/metre, the 26.5GHz on the scales at 50g/metre and the featherweight 40 & 50GHz at a mere 33g/metre. Standard lengths are all available from stock with short delivery times for custom assemblies.
