RF Transmitter Procurement Notes

Verify component status as the MICRF103YM is classified as obsolete and no longer manufactured by Microchip Technology. Confirm availability through authorized distributors for remaining stock or identify approved substitute components for new designs. Ensure compatibility with existing circuit layouts when sourcing replacement units from secondary markets.

RF Transmitter Selection Notes

Select this component only for maintenance or retrofit projects requiring specific legacy specifications. Evaluate alternative modern RF transmitters for new product development due to obsolescence. Verify that the 800 MHz to 1 GHz frequency range aligns with regional regulatory requirements for the intended deployment location.

RF Transmitter Part Context

The MICRF103YM belongs to the Micrel/Microchip family of low-power RF transmitters. Originally developed by Micrel before its acquisition by Microchip, it utilizes proprietary QwikRadio architecture. This series targets simple, cost-effective wireless control solutions requiring minimal external components for basic telemetry and control tasks.
