RF Amplifiers Procurement Notes

This component is officially listed as obsolete and no longer in production by the manufacturer. Verification of availability requires checking authorized distributors for remaining stock or approved replacement parts. Ensure that any sourced units are genuine and match the specific TR2G suffix requirements for tape-and-reel packaging compatibility.

RF Amplifiers Selection Notes

Select this part for low-frequency RF amplification tasks up to 500 MHz where moderate gain and standard noise figures are sufficient. Consider the SOT-143-4 footprint constraints during PCB layout. Due to its discontinued status, engineers should evaluate alternative components from the same family or competitors that offer updated supply chain stability while maintaining similar electrical characteristics.
