FMSW1104

RF Switches Overview

The FMSW1104 is an SMA reflective SP4T coaxial switch manufactured by Fairview Microwave using GaN high-power PIN diode technology. It operates from DC to 6 GHz and is rated for 40 Watts of power handling with a switching speed of less than 100 nanoseconds.

RF Switches Feature Summary

• Utilizes GaN high-power PIN diode technology for robust signal switching
• Provides four-port single-pole-throw (SP4T) configuration with reflective design
• Supports high power handling capabilities up to 40 Watts

RF Switches Applications

• RF test and measurement systems requiring high-power switching
• Wireless communication infrastructure signal routing
• Aerospace and defense radar system configurations

RF Switches Procurement Notes

Verify the specific datasheet version and electrical characteristics directly with Fairview Microwave or authorized distributors before procurement. Confirm that the 40-watt rating and 6 GHz upper frequency limit align with your system requirements, as specifications may vary by production batch or regional compliance standards.

RF Switches Selection Notes

Select this component when a reflective SP4T topology is required for frequencies up to 6 GHz. The GaN PIN diode construction makes it suitable for applications demanding higher power handling compared to standard silicon-based switches. Ensure interface compatibility with SMA connectors and verify thermal management needs for continuous 40-watt operation.

RF Switches Part Context

This model belongs to Fairview Microwave's line of high-performance RF coaxial switches. It complements other models like the FMSW1101, which offers similar technology but with different port counts and frequency ranges, allowing engineers to scale switching complexity while maintaining high-power reliability in microwave circuits.

RF Switches Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Evaluate the FMSW1101 for alternative switching configurations if the SP4T form factor is not strictly required.
