RF Amplifiers Procurement Notes

This component is officially classified as obsolete by the manufacturer. Availability is restricted to remaining stock or secondary market sources rather than direct production runs. Verify part authenticity and condition carefully when sourcing from non-primary distributors due to end-of-life status. Ensure compatibility with existing design specifications before procurement.

RF Amplifiers Selection Notes

Select this component only for legacy designs requiring 500 MHz to 18 GHz amplification with specific 12 dB gain characteristics. Consider the 5 V supply requirement and 58 mA current draw during power budgeting. Evaluate thermal management needs given the small 0402 footprint. Confirm that the obsolete status aligns with long-term support requirements for the target application.
