Procurement Notes

Verify the specific suffix 'Z' indicates RoHS compliance when sourcing. Confirm the package type matches the 24-VFQFN footprint required for the design. Ensure the supplier documentation references the official pSemi datasheet for the PE43702 series to validate electrical specifications and pinout compatibility.

Selection Notes

Select this component for applications requiring a wide dynamic range up to 31.75 dB within a compact form factor. The DC-to-4.0 GHz bandwidth suits general-purpose RF attenuation needs. Consider the CMOS interface requirements for system integration and verify that the thermal performance meets the operating environment constraints.

Part Context

This part belongs to the pSemi UltraCMOS family of RF digital step attenuators. These devices are built on silicon-on-insulator technology to deliver superior linearity and low power consumption compared to traditional approaches. The PE43702 represents a 7-bit solution designed for versatile signal control in modern communication systems.

Replacement Considerations

The PE43702MLI is the non-RoHS version of this component. Other models in the series include the PE43703 and PE43704, which offer different attenuation ranges or bit resolutions.
