RF Amplifiers Procurement Notes

This component is officially classified as obsolete by the manufacturer. Availability is restricted, and sourcing may require checking secondary market channels or verifying specific end-of-life notifications. Designers should prioritize replacement strategies due to limited long-term supply assurance.

RF Amplifiers Selection Notes

Select this part for applications requiring high linearity and significant output power in the 1.7–2.7 GHz band. Verify that the system can accommodate the 5 V supply requirement and 750 mA current draw. Ensure thermal management solutions support the specified power dissipation capabilities for sustained operation.

RF Amplifiers Part Context

The ALM-32220 series belongs to Broadcom's Meranti family of RF power amplifiers. This specific model represents a 2-watt class device optimized for general-purpose wireless applications. It is distinct from lower-power variants like the ALM-31222, offering higher output power capabilities suitable for base station or repeater environments.

RF Amplifiers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, engineers must evaluate alternative components based on matching electrical specifications such as frequency range, gain, and linearity requirements.
