RF Transmitter Procurement Notes

Verify part status as active before procurement. Confirm package variant matches design requirements, as the base number covers both TFSOP and MSOP forms. Check RoHS compliance documentation for specific environmental regulations. Ensure supply chain sources provide official datasheets to validate electrical parameters against system specifications prior to integration.

RF Transmitter Selection Notes

Select this component for UHF band applications requiring moderate output power and low current consumption. Compare pinout compatibility if replacing older Micrel versions. Consider thermal performance within the specified industrial temperature range. Evaluate board space constraints due to the small outline package dimensions relative to alternative transmitter options.
