Description
Overview
The Keysight U9400A is a solid state FET transfer switch designed for RF and microwave switching applications requiring exceptional isolation, fast switching speed, and minimal video leakage. Its broad frequency coverage from 300 kHz to 8 GHz, combined with industry-leading settling time, makes it particularly well-suited for testing sensitive RFIC components and demanding high-frequency test systems.
Key Features
- Exceptionally high port-to-port isolation of >100 dB to minimize crosstalk
- Broad operating frequency range from 300 kHz to 8 GHz
- Industry-leading settling time of 350 µs for improved throughput
- Very low video leakage of <5 mVpp reduces risk to sensitive RFIC components
- Integrated TTL-compatible driver eliminates external driver requirements
- Fast switching speed of 4 µs rise/fall time (typical)
Applications
- Sensitive RFIC component testing
- RF and microwave switching systems
- Instrumentation and signal routing
- High-isolation switching applications
