RF Front End (LNA + PA) Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm the operating temperature grade matches the '-I' designation for industrial ranges. Ensure the 14-TSSOP footprint aligns with PCB design requirements. Cross-reference the datasheet revision to confirm pinout consistency. Validate RoHS compliance status for environmental regulations.

RF Front End (LNA + PA) Selection Notes

Select this component for designs requiring integrated LF AFE functionality without external discrete components. Consider the 125kHz operation for standard automotive keyless entry protocols. Evaluate the 10kbps data rate against system latency requirements. Assess the 2V to 3.6V supply range compatibility with target power rails. Review the TSSOP package dimensions for space-constrained layouts.
