microbend® KR
True Flexible Coaxial Cable Assemblies
Product Description
microbend® KR has the benefits of the microbend® cable assembly but with 40GHz, solderless 2.9mm plug connectors on each end. microbend® KR replaces custom length, pre defined bend configuration .047 semi-rigid cable with standard length, true flexible coax cable for use as internal interconnections between RF modules in communications and high bandwidth switching systems.
Product Features
- Precision 2.9mm microbend® plug connectors
- Lower insertion loss than .047 semi-rigid cable
- Stock delivery on standard lengths
- Eliminates need for costly right angle connectors
|
- Triple shielded for high isolation
- Frequency range up to 40 GHz
- Guaranteed 10 lb. pull force
- 100% lead free

Phase Versus Flexure Reference Data
Astrolab performed phase tests on hundreds of microbend® cable assemblies. Following are two standard Astrolab tests with the corresponding data. In test one microbend® KR–5 assembly's were flexed 90° in a 0.1 inch radius directly behind the connector. In test two, microbend® KR–5 assembly's were flexed 180° with a 0.25 inch radius in the middle. Typical data is listed here:
