The Agilent/Keysight 5086-7539 is a hybrid solid-state transfer switch engineered for RF and microwave test equipment integration. It combines GaAs SPDT switches for low-frequency isolation with shunt PIN diodes for high-frequency performance, delivering broadband switching across DC to 6 GHz with extended operation to 8 GHz in select versions.
Technical Specifications
• Switch Type: Hybrid solid-state architecture with GaAs SPDT and PIN diode elements
• Frequency Range: DC to 6 GHz (8 GHz in extended versions)
• Insertion Loss: 2–4 dB across DC to 6 GHz
• Isolation: Greater than 100 dB
• Control Voltage: 24 V (center)
• Construction: Wire-bonded substrate assembly with spring-finger center conductor, threaded connector shield, and spacer tube retention. Glass bead pressed into housing.
– Key Features
• High isolation exceeds 100 dB for superior signal rejection
• Moderate insertion loss (2–4 dB) suitable for test set applications
• Dual switching topology optimizes performance across frequency spectrum
• Mechanical compatibility with 24 V control architecture
• Hybrid design balances low-frequency and microwave performance in single assembly
– Typical Applications
• Vector network analyzer integration
• S-parameter measurement systems
• RF test and characterization equipment
• Broadband switching and signal routing in laboratory instruments
– Compatibility & Integration
The 5086-7539 is OEM-integrated into Agilent/Keysight instruments including the 8753ES and 8753E Vector Network Analyzers, as well as the 85046A/B and 85047A S-Parameter Test Sets. Component-level integration requires 24 V control interface and standard RF connector termination.
