MegaPhase’s AlumiBendTM series cable is a lightweight alternative to standard semi-rigid coax, offering the advantages of reduced weight and small form factor. AlumiBend cable assemblies are available in three sizes: 0.047 in. (model AL047), 0.086 in. (AL086) and 0.141 in. (AL141), with frequency responses to 90, 50 and 34 GHz, respectively. Depending on the model, the cable assemblies can be fitted with 1.85 mm, 2.4 mm, 2.92 mm, 3.5 mm, SMA, TNC or type N connectors.
The standard AlumiBend series is fabricated with a solid silver-plated copper inner conductor and silver-plated aluminum jacket, which is 40 percent lighter than an equivalent cable with a copper jacket. The cables are easily bent to the desired shape, which remains consistent after bending. The bend radii are 0.125 in. (AL047), 0.25 in. (AL086) and 0.50 in. (AL141).
The AlumiBend’s low-loss cable uses a microporous dielectric, which provides low attenuation, an operating temperature range from -55°C to +250°C and more linear phase stability over temperature, compared to solid PTFE semi-rigid cables. The typical insertion loss at the upper end of the frequency range is less than 3 dB/ft at 90 GHz (AL047), under 1.5 dB/ft at 50 GHz (AL086) and below 0.6 dB/ft at 34 GHz (AL141).
AlumiBend cables are space-qualified and manufactured to meet the European Space Components Coordination (ESCC) 3408 specifications. In addition to space, the AlumiBend will support electronic warfare, telecommunications and other RF, microwave and mmWave applications, whether on the ground, sea or air.
With more than 500 active customers in 30 countries, including the U.S. government and its allies, MegaPhase has a long heritage. The AlumiBend cable series is another link in a long chain of innovations from this 23-year-old Pennsylvania company.
