RF Receivers Procurement Notes

Verify the specific suffix FT1 confirms the tube packaging format when ordering. Ensure the J1 variant matches the required frequency band configuration for your design. Cross-reference the datasheet to confirm pinout compatibility with your PCB layout. Validate that the 12 mA receive current aligns with your system's power budget constraints before finalizing procurement.

RF Receivers Selection Notes

Select this component for designs requiring dedicated FSK reception in the 315/433 MHz ISM bands. Consider the 16-pin TSSOP package size for space-constrained layouts. Evaluate the 400 kHz bandwidth against your data rate needs. Ensure the microcontroller interface supports the required SPI or parallel communication protocols for data extraction.
