RF Switches Procurement Notes

Verify the complete part number including the MLBA-Z suffix to ensure correct packaging and RoHS compliance status. Confirm that the 75-ohm impedance specification aligns with your system requirements, as this component is specifically optimized for CATV applications rather than standard 50-ohm RF paths. Check the latest datasheet revision for any updates on operating conditions or pin configurations before finalizing procurement orders.

RF Switches Selection Notes

Select this component when a 75-ohm impedance match is required for CATV or broadband applications up to 2.2GHz. The absorptive topology provides better return loss compared to reflective switches. Ensure the design accommodates the 12-QFN package dimensions and thermal requirements. This switch is ideal for designs prioritizing high linearity and low insertion loss in compact spaces.

RF Switches Part Context

The PE42721 belongs to pSemi's portfolio of HaRP™ enhanced switches, leveraging UltraCMOS® technology. It is distinct from 50-ohm variants by its specific 75-ohm impedance matching, making it specialized for cable television and broadband infrastructure. The MLBA-Z suffix indicates the specific tape-and-reel packaging configuration available through distributors.

RF Switches Replacement Considerations

Direct replacements must maintain 75-ohm impedance and SPDT topology. Verify compatibility with existing PCB footprints for the 12-QFN package. Ensure substitute components support the same 2.2GHz frequency range and similar linearity metrics for CATV applications.
