microbend® R True Flexible Coaxial Cable Assemblies
Product Description
microbend® R replaces .047 custom semi-rigid cable with standard, flexible "bend to the end" cables eliminating the need for predefined custom lengths and bend configurations. microbend® R was designed for use as internal point-to-point interconnections between modules in microwave and fiber optic switching systems. microbend® R features include lower loss than .047 semi-rigid cable, a minimum bend radius of 0.060 inches, triple shielding for high isolation, an FEP jacket for added protection, a frequency range up to 26.5 GHz, and a guaranteed 10 lbs. pull force.
Product Features
- Precision stainless steel SMA plug connectors (Patented - US Patent Office)
- Connector pull strength 70% stronger than standard microbend and torque resistant utilizing minibend R technology
(Patented - US Patent Office)
- Stock delivery on standard lengths
|
- Lower insertion loss than .047 semi-rigid cable
- Eliminates need for costly right angle connectors
- Triple shielded for high isolation
- Frequency range up to 26.5 GHz

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® R–5 assembly's were flexed 90° in a 0.15 inch radius directly behind the connector. In test two, microbend® R–5 assembly's were flexed 180° with a 0.25 inch radius in the middle. Typical data is listed here:
