RF Transmitter Procurement Notes
Verify component authenticity through authorized Infineon channels due to discontinued status. Confirm RoHS compliance requirements as the part is non-compliant. Validate package integrity and pin alignment against the 10-TFSOP specification before integration. Ensure supply voltage limits are strictly maintained during procurement planning.
RF Transmitter Selection Notes
Select this component for low-power applications requiring simple ASK or FSK modulation at 345 MHz. Consider the 7 mA transmission current and 2.1 V minimum supply for battery-operated designs. Evaluate the 10-TFSOP footprint constraints against PCB layout requirements. Assess thermal performance within the specified operating temperature range.
RF Transmitter Part Context
This RF transmitter belongs to Infineon's portfolio of integrated radio frequency solutions. It complements other wireless communication components by providing a compact, high-integration option for short-range data transmission. The device fits within the broader category of single-chip transmitters designed for industrial and consumer electronics.
RF Transmitter Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing circuit designs if considering alternative RF transmitters from the same manufacturer.
