RF Transmitter Procurement Notes

Verify component status as this part may be discontinued or obsolete. Confirm availability through authorized distributors or approved substitute channels. Ensure compatibility with existing design constraints before procurement. Check for RoHS compliance status if required by specific project standards. Validate that the 14-SOIC package matches the target PCB footprint.

RF Transmitter Selection Notes

Select this component for low-cost, short-range wireless applications requiring ASK or OOK modulation. Consider the limited output power and data rate when designing the link budget. Ensure the system voltage falls within the 1.8V to 4V operational range. Verify that the 300-470MHz band is permitted in the target deployment region.

RF Transmitter Part Context

This device belongs to Microchip's QwikRadio family of low-power RF transceivers. It is designed for simple, cost-effective wireless communication solutions. The component integrates the transmitter circuitry into a single chip, reducing external component count. It targets markets requiring basic remote control functionality without complex protocol stacks.

RF Transmitter Replacement Considerations

MICRF112YMM and MICRF113YM6-TR are listed as potential substitutes. Verify pinout compatibility and electrical parameter alignment before substitution. Confirm that the replacement parts meet the same frequency and modulation requirements.
