RF Multiplexers Procurement Notes

Verify that the specific suffix A1 matches the required electrical specifications against the official datasheet, as variations may exist within the series. Confirm RoHS3 compliance status and MSL rating requirements for your assembly process. Ensure the 0603 footprint aligns with your PCB layout constraints. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

RF Multiplexers Selection Notes

Select this component when designing dual-band transceivers requiring simultaneous or switched operation between 2.4 GHz ISM and 5 GHz UNII/WLAN bands. Consider its low insertion loss profile for sensitivity-critical links. Evaluate the 0603 package size against available board real estate. Compare return loss specifications against system interference requirements before finalizing the design.
