RF Switches Procurement Notes

Verify the specific ordering suffix and package variant against official pSemi documentation before procurement. Confirm that the selected component matches the required SP8T configuration and voltage specifications. Ensure compliance with RoHS standards and check for any recent design changes or obsolescence notices directly from the manufacturer's official channels.

RF Switches Selection Notes

Select this component when an SP8T topology is required for frequencies up to 8 GHz. Consider its absorptive nature for improved return loss compared to reflective switches. Evaluate the integrated control logic benefits for simplified system design. Verify thermal management requirements given the extended temperature range and power dissipation characteristics inherent to the UltraCMOS technology.
