– Key Features
• High isolation performance exceeds 70 dB at maximum frequency
• Low insertion loss specification maintains signal fidelity across the passband
• Metal chassis construction supports both rack and benchtop deployment
• Impedance-matched 50 Ohm ports minimize reflections
• Switching speed and RF power handling vary by unit configuration and control voltage
– Typical Applications
• Automated test equipment (ATE) systems
• RF and microwave signal distribution networks
• Component and subsystem characterization
• Matrix switching configurations for multi-signal routing
• High-frequency test system integration
– Compatibility & Integration
The 87104A integrates into RF and microwave test platforms using standard logic-level control signals or dedicated switch drivers. Type N Female connectors provide direct interface compatibility with industry-standard RF instrumentation. Specific control voltage, logic levels, switching timing, and maximum RF power ratings are unit-dependent and require verification against your particular configuration.
