RF Transmitter Procurement Notes
Verify the specific suffix (+T vs -T) against the manufacturer's official documentation to confirm lead-free status and tape-and-reel specifications. Ensure the ordering part number matches the exact package variant required for your PCB layout. Cross-reference the datasheet revision date to confirm compatibility with current manufacturing standards.
RF Transmitter Selection Notes
Select this component when a compact, low-cost transmitter is needed for short-range wireless control. It is suitable for designs requiring fixed-frequency operation without complex external synthesizers. Consider the 300-450MHz band availability in your target region before finalizing the design.
RF Transmitter Part Context
This part belongs to the Maxim Integrated VHF/UHF transmitter family. It is designed as a cost-effective solution for simple on-off keying applications. The series focuses on minimizing external component count by integrating the PLL and RF output stage into a small footprint.
