RF Amplifiers Procurement Notes

This component is officially listed as obsolete or end-of-life by the manufacturer. Availability is restricted to existing stock or secondary market sources. Verify part authenticity and condition carefully when sourcing from distributors, as original manufacturing has ceased. Check specific supplier documentation for lot dates and handling requirements.

RF Amplifiers Selection Notes

Select this component only for legacy designs requiring specific 1.575/1.602 GHz performance characteristics. Due to its obsolete status, new production integration is not recommended. Evaluate alternative active components that offer similar gain and noise specifications if redesigning current hardware architectures.

RF Amplifiers Part Context

Part of the Broadcom ALM series of radio frequency amplifiers designed for wireless communication applications. This specific model targets global positioning system implementations, offering a balance of gain and noise performance within a small footprint suitable for mobile and embedded navigation devices.

RF Amplifiers Replacement Considerations

No direct public substitute part numbers are confirmed for this obsolete component. Designers must evaluate functional equivalents from other manufacturers that match the 1.575 GHz frequency range, 19.1 dB gain, and 8-MCOB package constraints.
