RF Multiplexers Procurement Notes

This component is officially listed as Last Time Buy or End of Life by the manufacturer. Availability is restricted to existing inventory only; no new production will occur once current stock is depleted. Verification of specific lot dates and authenticity through authorized channels is essential due to the discontinued status. Engineers should plan for immediate obsolescence management and transition strategies.

RF Multiplexers Selection Notes

Designers must verify that the required frequency bands align precisely with the 824-960MHz and 1.71-2.17GHz specifications. The 0603 package size imposes strict constraints on board layout and soldering processes. Since the part is discontinued, alternative components with matching electrical parameters and compatible footprints must be identified to ensure long-term supply chain stability for production runs.

RF Multiplexers Part Context

This device belongs to the TDK DPX series of RF diplexers, which are specialized passive components used to combine or separate radio frequency signals. These components are critical in mobile handsets to allow simultaneous operation across different cellular bands while maintaining signal integrity and preventing interference between transmitter and receiver paths.
