• Recommended bend radius of 2.5 cm during normal use preserves phase and magnitude stability while reducing torsional stress.
• Temperature range of -55°C to +125°C accommodates both laboratory and field measurement environments.

– Typical Applications

• Network analyzer test ports and interconnections
• Precision RF and microwave device characterization
• High-frequency component testing up to 110 GHz

– Compatibility & Integration

Connectors comply with IEEE 287 Precision Connector Standard. Use back-up wrench during connection to prevent coupling damage. Inspect connector contact surfaces for contamination before deployment. The 85059A calibration kit provides cleaning and inspection tools for maintenance. Spare cable sets are recommended to minimize downtime.
