High Velocity, Low Loss Cable Assemblies from DC to 50 GHz for T&M

AtlanTecRF has introduced the ACH series of high velocity cable assemblies available in frequency ranges of DC to 18 GHz, DC to 26.5 GHz, DC to 40 GHz and DC to 50 GHz. With a 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 with the option for custom assemblies on request. Overall cable O/D ranges from 7.8 mm for the 18 GHz designs to 3.6 mm for the 40 GHz and 50 GHz versions.

All series have an operating temperature range of -55 to +165 C 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 to +125 C temperature range.

In terms of insertion loss an 18 GHz, 0.5 metre assembly exhibits only 0.4 dB at the top of its frequency range while the 40 GHz 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 40 GHz to over 700 watts for the ACH-CA18 cable at 6 GHz. All connectors are stainless steel, SMA male up to 26.5 GHz, 2.92 mm to 40 GHz and 2.4 mm to 50 GHz.

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