RF Amplifiers Procurement Notes

This component has been officially declared obsolete by Broadcom Limited as per product obsolescence notifications dated December 1, 2017. Procurement must focus on verifying the authenticity of remaining stock from authorized distributors or secondary market sources. Buyers should confirm the specific manufacturing date code and storage conditions to ensure reliability, as availability is limited to existing inventory rather than new production runs.

RF Amplifiers Selection Notes

Engineers selecting this part must account for its discontinued status when designing new hardware. The ALM-80210-BLKG offers a specific combination of gain, linearity, and bandwidth suitable for legacy or maintenance projects involving CDMA, LTE, W-CDMA, and WiMAX technologies. Due to the lack of future production, alternative solutions with similar RF performance characteristics and compatible pinouts should be evaluated for long-term supply chain stability.

RF Amplifiers Part Context

The ALM-80210-BLKG belongs to Broadcom's portfolio of radio frequency amplifiers intended for wireless infrastructure. It is categorized as a standard product that has reached end-of-life. The device integrates variable gain functionality into a compact 10-MCOB package, addressing the need for efficient signal conditioning in multi-standard mobile communication base stations and access points operating in the cellular frequency bands.

RF Amplifiers Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation.
