RF Multiplexers Procurement Notes

Verify the specific datasheet version, as manufacturer documentation may vary slightly between distributors. Confirm that the 0805 footprint matches the target PCB layout, noting the eight-pad configuration. Ensure the operating temperature range meets the environmental requirements of the final assembly. Check for any recent product lifecycle notices regarding obsolescence or design-in restrictions.

RF Multiplexers Selection Notes

Select this component when a compact solution is required for separating 2.4GHz and 5GHz ISM bands. The choice depends on the need for low insertion loss and small form factor in space-constrained designs. Evaluate the trade-off between the specific frequency isolation provided by this model versus other variants in the DPX series that may offer different bandwidth combinations.

RF Multiplexers Part Context

This part belongs to the TDK DPX series of LTCC diplexers. These components are engineered for high reliability in consumer electronics.
