RF Transmitter Procurement Notes

Verify the specific suffix and tape & reel packaging details against current distributor catalogs. Confirm that the component status remains active as obsolescence notices may affect long-term availability. Ensure compatibility with existing board layouts regarding the TQFN-28-EP footprint and thermal pad requirements before finalizing procurement orders.

RF Transmitter Selection Notes

Select this component when a high-power single-chip solution is required for 868/915MHz ISM bands. It is suitable for designs needing integrated ASK or BPSK modulation without external mixers. Consider the 200mW output capability for range requirements and verify that the operating voltage aligns with the system power budget.

RF Transmitter Part Context

This part belongs to the MAX2902 series of single-chip RF transmitters from Maxim Integrated. It is specifically engineered for cost-effective and compact wireless solutions in unlicensed ISM bands. The device simplifies RF front-end design by integrating the oscillator, modulator, and power amplifier into one package.

RF Transmitter Replacement Considerations

Check for direct pin-to-pin replacements within the same product family. Verify if alternative packages offer identical electrical performance. Ensure any substitute maintains support for the required modulation types and frequency bands.
