RF Transmitter Procurement Notes

Verify the specific manufacturer source, as Analog Devices Inc. and Maxim Integrated are referenced interchangeably in available data. Confirm that the component status is active or obsolescence details are understood before procurement. Ensure the 48-TQFN package dimensions match your PCB footprint requirements. Check for RoHS compliance documentation if required by your manufacturing standards. Validate the supply voltage range compatibility with your system's power management architecture.

RF Transmitter Selection Notes

Select this component when designing for single-band cellular applications requiring integrated modulation and amplification. It is suitable for systems needing reduced bill-of-materials count by combining multiple RF functions. Consider the 90mA transmit current for power budget calculations. Ensure the 2.7V-3.3V supply range aligns with your battery-powered device constraints. Evaluate the 48-pin TQFN package for thermal and spatial constraints in handheld designs.

RF Transmitter Part Context

This part belongs to the family of RF transmitters from Maxim Integrated, now part of Analog Devices. It is specifically engineered for the cellular market, targeting legacy CDMA and TDMA networks. The ETM+ suffix indicates a lead-free, halogen-free version in a 48-WFQFN package. It serves as a key component in the RF front-end chain, handling baseband-to-RF conversion and signal amplification.
