RF Receivers Procurement Notes

Verify the specific suffix 'C40' against official Skyworks documentation to confirm band coverage and electrical characteristics. Ensure the component matches the required 20-QFN package dimensions and interface specifications for your PCB layout. Confirm availability status as distribution data may vary.

RF Receivers Selection Notes

Select this component when multi-band analog radio reception is required in a small form factor. The low current consumption and wide supply voltage range make it suitable for battery-powered applications. Verify that the 3-wire interface compatibility aligns with the host microcontroller's communication protocols.

RF Receivers Part Context

This part belongs to the Si473x series of silicon radios from Skyworks Solutions. These devices are designed to replace traditional discrete tuner solutions, offering high integration and reduced board space. The series typically includes variants with different package options and band configurations.

RF Receivers Replacement Considerations

Check for direct substitutes such as the SI4734-D60-GMR or SI4734-D60-GM if the C40 variant is unavailable. Verify that alternative suffixes maintain identical pinout and functional parameters before substitution.
