Ultra flexible low loss test cable range
Key to its ultra flexible performance is the unique cable construction in five layers from a silver plated copper centre conductor through low density PTFE dielectric, silver plated copper shield and silver plated copper outer shield, to the polyurethane jacket. This last ingredient holds the key and although not having the operating temperature range of more traditional materials, such as FEP, it is considerably more flexible and still operates over the full military range of -55 to +85ºC.
This flexibility, demonstrated by the minimum bend radius of just 20mm, not only improves ease of use in the test environment, along with very low stress levels on the cable, it also enables the test engineer to create a higher density test set up, saving space and reducing testing time.
With operating frequency ranges up to 26.5 GHz, the APC cable assemblies are available with SMA male connectors as standard and also with type N male with 18 GHz versions.
Standard stock lengths offered are from 0.5 metre to 5 metres in 0.5 metre intervals. Custom lengths are also available up to 25 metres and beyond. Insertion loss is 1.0 dB per metre at 6 GHz and 2.5 dB per metre at 26.5 GHz, plus stability is ±3 degrees and shielding effectiveness is greater than 90 dB.
Speaking at the product launch at AtlanTecRF’s R&D Centre in Braintree in the UK, CEO Geoff Burling said “Again in this new test cable design we have put the user at the forefront of our thinking in providing an incredibly flexible cable with excellent RF performance, typified by its velocity of propagation of 76 percent”.
All assemblies are RoHS compliant and individual test data is also available.
