RF Amplifiers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix TR1G indicates tape and reel packaging. Check for End-of-Life status as indicated by lifecycle data. Ensure compatibility with existing PCB footprints for the SOT-143 package. Validate that the obsolete status does not impact long-term supply requirements.

RF Amplifiers Selection Notes

Select this component for designs requiring moderate gain in the sub-700 MHz range. Consider the 4 V supply requirement and 20 mA current draw for power budgeting. Evaluate the 3 dB noise figure against system sensitivity needs. Compare OIP3 performance with alternative amplifiers if linearity is critical. Verify thermal management capabilities given the high maximum operating temperature rating.
