RF Mixers Procurement Notes

Verify the specific ordering suffix and revision level against the manufacturer's official documentation before procurement. Confirm that the intended application frequency aligns with the specified 1.7 GHz to 2.2 GHz operational range. Ensure thermal management strategies account for the power dissipation characteristics of the QFN-24 package during continuous operation.

RF Mixers Selection Notes

Select this component when a compact solution combining mixing and LO amplification is required for sub-3 GHz wireless standards. Consider the 8 dB noise figure and 120 mA supply current as key constraints for system design. Evaluate the QFN-24 thermal pad requirements for adequate heat dissipation in dense PCB layouts compared to alternative discrete solutions.

RF Mixers Part Context
