– Key Features
• Minimal VSWR performance ensures minimal signal reflections and impedance mismatch losses
• Flat attenuation response across the operating band minimizes frequency-dependent insertion loss variation
• Low DC resistance enables high DC current operation
• Wide operating and storage temperature range supports field and laboratory deployments
• Unibody construction delivers mechanical stability under thermal cycling and vibration
– Typical Applications
• Signal level adjustment in RF test systems
• Impedance matching and transmission line termination
• Protection of sensitive RF and microwave components from excessive signal levels
• Bench and automated test equipment configurations
– Compatibility & Integration
The SAT-10 integrates into 50 Ohm RF systems via SMA connectors. DC-passing design permits simultaneous RF signal and DC bias delivery through the same transmission path, simplifying circuit topologies that require bias injection or monitoring.
