RF Multiplexers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required frequency tolerances and packaging formats. Confirm that the procurement channel provides traceable documentation for RoHS3 compliance and MSL classification. Cross-reference the DigiKey or Mouser part numbers with the official TDK catalog to avoid discrepancies in revision levels or manufacturing origin before finalizing orders.

RF Multiplexers Selection Notes

Select this component when designing circuits requiring simultaneous operation in the 698-960MHz and 1.71-2.7GHz ranges. Ensure the design accommodates the 0805 SMD package dimensions and thermal requirements. Consider the specified insertion loss and return loss values to maintain system efficiency. Verify that the 50 Ohm impedance matches the surrounding RF transmission lines and filter networks for optimal signal integrity.
