FMSW6218

RF Switches Overview

The FMSW6218 is a high-power, field-replaceable coaxial switch manufactured by Fairview Microwave. It utilizes PIN diode technology to provide SP8T switching functionality within the 500 MHz to 40 GHz frequency range. The component is rated for +20 dBm power handling and features an absorptive design to minimize reflections. Electrical specifications include a maximum insertion loss of 10 dB and isolation of 50 dB. The unit employs solder pin termination for secure mounting and is packaged individually in a bag.

RF Switches Feature Summary

• SP8T configuration utilizing PIN diode switching technology
• Absorptive design architecture for signal integrity
• Field-replaceable construction for maintenance flexibility
• High-power rating suitable for demanding RF environments

RF Switches Applications

• Test and measurement instrumentation requiring high-frequency switching
• Aerospace and defense radar systems
• Telecommunications infrastructure testing
• Automated test equipment (ATE) setups

RF Switches Procurement Notes

Verify that the specific application environment supports the 10 dB insertion loss specification, as this value is relatively high compared to standard mechanical switches. Confirm that the +20 dBm power rating aligns with system signal levels to prevent device damage. Ensure the solder pin termination method is compatible with the target PCB or chassis layout, as this affects installation requirements and thermal management strategies.

RF Switches Selection Notes

Select the FMSW6218 when operating frequencies extend up to 40 GHz and high power handling is required. The absorptive nature makes it suitable for applications where reflection control is critical despite higher insertion loss. Consider the field-replaceable aspect if long-term serviceability is a priority. Evaluate the SP8T topology against system routing needs to ensure sufficient port count without excessive complexity.
