RF Switches Procurement Notes

Verify the specific suffix code against official Skyworks documentation to confirm pinout and electrical characteristics match project requirements. Confirm RoHS compliance status through current datasheets. Ensure the supplier provides valid traceability documents. Check for any regional distribution restrictions or export control classifications applicable to this component before finalizing orders.

RF Switches Selection Notes

Select this component for designs requiring SPDT switching in the 400 MHz to 3.8 GHz band. The 25 dB isolation specification suits applications needing moderate signal separation. The small 1.1 x 1.1 mm footprint is suitable for space-constrained mobile and IoT devices. Verify that the DC blocked feature aligns with the biasing requirements of the connected RF front-end modules.

RF Switches Part Context

This part belongs to the Skyworks RF switch portfolio, specifically targeting cellular and wireless communication markets. It serves as a compact solution for antenna switching and signal routing in modern mobile handsets and base stations. The SPDT topology allows connection between one common port and two selectable ports, facilitating simple signal path management in multi-band transceivers.

RF Switches Replacement Considerations

SKY13582-676LF is a related component in the same series but offers SP3T configuration instead of SPDT. Verify pin compatibility and functional differences before substitution.
