RF Receivers Procurement Notes

Verify the specific suffix 'B20' against official Skyworks documentation to confirm pinout and functional compatibility, as variations exist within the SI4734 family. Confirm that the 20-QFN package matches your PCB footprint requirements. Check current lifecycle status, as this part may be obsolete or discontinued depending on the manufacturing date. Ensure RoHS compliance verification aligns with your regulatory standards before finalizing procurement.

RF Receivers Selection Notes

Select the SI4734-B20-GM when broad broadcast band coverage including SW-LW is required alongside FM/AM. Compare receive current specifications against other family members like the SI4734-D60 variants if power efficiency is critical. Verify that the 2.7V minimum supply voltage meets your system's power rail capabilities. Consider the 20-QFN package size constraints relative to available board space compared to larger packages like SSOP options.
