RF Amplifiers Procurement Notes

This component is officially listed as End-of-Life (EOL) by the manufacturer. Availability is restricted, and distributors may not stock units in all regions. Verify obsolescence status and lead times carefully before design finalization. No new production is guaranteed. Check for official Product Change Notices or replacement recommendations from Broadcom Limited prior to procurement attempts.

RF Amplifiers Selection Notes

Select this part only if silicon-based RF amplification at approximately 3.5 GHz is required. Ensure the design accommodates the 750 mA supply current and 4.125 W power dissipation limits. The +150°C maximum junction temperature allows for high-thermal environments. Consider that the EOL status necessitates long-term supply risk assessment. Verify compatibility with 50-ohm system impedance and SMD/SMT assembly processes.

RF Amplifiers Part Context

The ALM-31322-BLKG belongs to the Meranti series of RF amplifiers manufactured by Broadcom Limited. It is categorized under Wireless & RF Integrated Circuits. The device represents a specific silicon implementation for general-purpose applications, distinct from GaAs front-end modules or switch components found in other Broadcom product lines. Its specifications target mid-frequency RF bands.

RF Amplifiers Replacement Considerations

No public confirmed substitute part numbers are documented for this specific model. As the component is End-of-Life, engineers must evaluate alternative RF amplifiers with matching 3.5 GHz frequency, 13.2 dB gain, and similar OIP3 characteristics. Consult Broadcom technical support for potential family replacements or updated component recommendations.
