SKY19237-001

RF Switches Overview

The SKY19237-001 is a triple-shunt, single-pole, single-throw (3xSPST) RF switch IC designed for operation within the 0.7 to 2.7 GHz frequency range. Manufactured by Skyworks Solutions Inc., this component utilizes a wafer level chip scale package (WLCSP) in an 11-UFBGA configuration. The device integrates logic and bias blocks, classifying it as a MIPI-compatible switch suitable for general-purpose RF applications requiring compact form factors.

RF Switches Feature Summary

• Triple-shunt architecture providing three independent SPST switching channels
• Integrated control logic and bias block simplifying system design
• Wafer level chip scale package (WLCSP) for minimal footprint

RF Switches Applications

• MIPI switch implementations
• General purpose RF signal routing
• Mobile wireless devices operating in 2.7GHz bands

RF Switches Procurement Notes

Verify component status carefully as the SKY19237-001 is listed as obsolete. Confirm availability through authorized distributors or secondary market sources. Ensure compatibility with existing board layouts due to the specific 11-UFBGA WLCSP package dimensions. Check RoHS3 compliance documentation if required for current manufacturing standards.

RF Switches Selection Notes

Select this component when a compact, multi-channel RF switch is needed for frequencies up to 2.7 GHz. The integrated logic reduces external control complexity. Consider the obsolete lifecycle status when planning long-term production. Evaluate isolation requirements as moderate isolation may necessitate duplexing strategies.

RF Switches Part Context

This part belongs to Skyworks' portfolio of RF switches targeting mobile and wireless applications. It represents a solution for integrating multiple switching functions into a small area using WLCSP technology. The 3xSPST configuration allows for managing multiple signal paths simultaneously within constrained space.

RF Switches Replacement Considerations

The SKY19237-001H is identified as a substitute equivalent. Verify electrical specifications and pinout compatibility before replacement. Both parts are classified as obsolete, requiring careful sourcing validation.
