RF Amplifiers Procurement Notes

This component is officially listed as obsolete by the manufacturer. Availability is restricted to remaining stock or secondary market channels. Verify RoHS compliance status through official documentation before integration. Ensure end-of-life notices are reviewed to assess long-term supply chain risks for production planning.

RF Amplifiers Selection Notes

Select this part for applications requiring integrated filtering and low noise performance at L1 GPS frequencies. Consider the 12-MCOB package dimensions for PCB layout constraints. Evaluate the 8 mA supply current against system power budgets. Confirm compatibility with existing 2.85 V supply rails and thermal requirements up to +85°C.

RF Amplifiers Part Context

The ALM-1412-TR1G belongs to Broadcom's family of RF amplifiers tailored for wireless communication systems. It serves as a specialized solution for global navigation satellite systems, specifically targeting the L1 band. The device represents a compact integration of amplification and filtering stages, reducing component count in receiver designs compared to discrete solutions.

RF Amplifiers Replacement Considerations

The ALM-1912-TR1G is a documented alternative within the same product family, featuring a 9-MCOB package. Both parts serve GPS applications but differ in physical footprint and potentially internal configurations. Verify pinout and electrical specifications when substituting.
