E und W-Band Test Assembly
The SUBMINIATURE Semirigid Cable Manufacture 1.0 - Cable assemblies for a frequency range up to 110 GHz
Take a look at our in-house manufacture and see how we make cable assemblies for a frequency range up to 110 GHz. At elspec group precision and highest quality is a must and that is why all materials are controlled before production. Especially for this cable assembly there is a bending plate on which the cables are bent to size in order to avoid damage to the cable. After finishing the assembly, each one is tested several times with a voltage of 100V to ensure electrical safety. In this video you can see the cable UT047, which is tinned with copper and has an outer diameter of 1.22mm, a transparent PTFE insulation and a magnetic steel-copper inner liner, which is silver-plated and has a diameter of 0.29mm. Steps shown here are cutting the cable, tinning and soldering, stripping, assembling the connector body and bending. Everything you see is handmade.
A microwave cable assembly with a cable of the Storm Flex® 047 series
Storm SF047EW offers engineers the proven longevity and robustness in their connection tasks. The bandwidth is fashion-free and optimized up to 110GHz. The flexible SF047EW cable is designed for the smallest bends corresponding to the insert damping / insertion loss addressed by waveguides. The assembly is equipped with the new 1.35mm connector system. This e-band connector can be used up to 90GHz and has closed the gap between the established 1.85mm connector and the 1. 0mm connector. The 1.85mm connector is designed up to 65GHz/ 70GHz and has a robust design. The 1.0mm series can be used up to 110GHz mode-free with the disadvantage that it can loosen during use.
The E-Band is the description for the frequency band 60-90 GHz, the W-Band 75-110GHZ.
At least 100 bending cycles are provided for the complete cable assembly for the dynamic radius. Note: Note the distance to the connector (15mm). The coaxial cable itself can withstand more than 1000 bends.
We conducted additional quality tests. These tests are part of the general 6-stage development process in which we perform cable properties such as bending, radius, phase vs. temperature, phase vs. bending, plug holder and other tests. We do this for all the cables we develop because we don’t know how every customer will use the cable. Therefore, we carry out a general test series to ensure that the cables work well in most test and measurement applications. For specific applications (e.g. in space) we carry out additional tests.
Test parameters: 9 samples, assembly length 460 mm, frequency bandwidth: 100GHz, mandrel: 25mm
a. In hibernation, the first values are taken.
b. Wrap 360 degrees clockwise and make measurements
c. Wrap the cable and make measurements
Note: The test was performed under extreme conditions to test the stability of the assembly. In case of a more normal bending of the cable (e. g. 20 degrees - 90 degrees) the amount of change (both phase and loss) is much lower.
