RF Detectors Procurement Notes

Verify the specific ordering suffix UR against the manufacturer's current product selection guide to ensure compatibility with required tape-and-reel specifications. Confirm that the NOPB designation aligns with current environmental compliance requirements for the intended assembly process. Cross-reference the datasheet revision date to validate technical parameters before finalizing procurement orders.

RF Detectors Selection Notes

Select this component when linear-in-dB detection accuracy is required for wideband RF signals. Ensure the operating frequency falls within the 450 MHz to 2 GHz range. Verify that the system power supply remains stable between 2.7 V and 5 V. Consider the small form factor of the 4-DSBGA package for space-constrained PCB layouts.

RF Detectors Part Context

This part belongs to the LMV225/LMV226/LMV228 family of RF power detectors manufactured by Texas Instruments. These devices are engineered for high-performance envelope detection in wireless infrastructure and portable equipment. The series provides consistent electrical characteristics across variants, differing primarily in packaging and reel configurations.

RF Detectors Replacement Considerations

LMV225URX/NOPB serves as a direct substitute with identical electrical specifications but utilizes a different reel configuration. LMV226UR/NOPB offers similar functionality with potential pinout or performance variations requiring schematic review. Always verify pin-to-pin compatibility and thermal characteristics before implementing substitutes.
