RF Receivers Procurement Notes

Verify the manufacturer designation as Analog Devices Inc./Maxim Integrated when sourcing this component. Confirm the specific suffix +CK3 matches the required packaging and compliance specifications. Ensure the part number corresponds to the active status listed in official catalogs. Cross-reference the datasheet for exact pinout and electrical characteristics before integration.

RF Receivers Selection Notes

Select this component for applications requiring a dedicated SDARS receiver with a 2.4GHz operating frequency. Consider the 44-WFQFN package for surface-mount assembly constraints. Evaluate the 180mA receive current against power budget requirements. Verify compatibility with the -40°C to 85°C industrial temperature range for the intended environment.

RF Receivers Part Context

This part belongs to the Maxim Integrated RF receiver family, now under Analog Devices. It is designed specifically for satellite radio applications. The device integrates necessary circuitry for direct reception without external downconversion stages. It represents a specialized solution within the broader portfolio of mixed-signal and RF components offered by the manufacturer.

RF Receivers Replacement Considerations

Consult official Analog Devices documentation for verified substitute part numbers. The MAX2140ETH+TCK3 shares similar specifications but may differ in packaging or compliance details. Do not assume interchangeability without verifying pinout and electrical parameter alignment against the original design requirements.
