PE43602MLI-Z

Overview

The PE43602MLI-Z is a 50-ohm, high-linearity, 6-bit RF digital step attenuator (DSA) from pSemi. It provides a total attenuation range of 31.5 dB in 0.5 dB steps across a frequency range of 9 kHz to 5 GHz. The device utilizes UltraCMOS technology and features both serial and parallel CMOS control interfaces. It is housed in a 24-VFQFN exposed pad package.

Feature Summary

• Provides precise digital attenuation with 6-bit resolution
• Supports both serial and parallel CMOS control interfaces
• Maintains high attenuation accuracy over frequency and temperature
• Utilizes UltraCMOS technology for high linearity

Applications

• RF signal path attenuation
• Test and measurement equipment
• Wireless communication systems
• Base station front-end modules

Procurement Notes

Verify the specific suffix 'MLI-Z' against the manufacturer's current product list to ensure availability and compliance with RoHS standards. Confirm that the 24-VFQFN package matches your PCB footprint requirements. Check for any recent production changes or obsolescence notices directly from pSemi documentation before finalizing procurement plans.

Selection Notes

Select this component when a wide bandwidth up to 5 GHz and fine 0.5 dB step resolution are required. Ensure the design supports the necessary CMOS control logic for either serial or parallel modes. Consider the thermal performance and power handling capabilities relative to the application's signal levels. Verify that the 50-ohm impedance matches the system architecture.

Part Context

The PE43602MLI-Z belongs to pSemi's UltraCMOS family of RF digital step attenuators. It is part of the broader PE436xx series, designed for applications requiring precise gain control. The device leverages proprietary semiconductor technology to achieve high performance in a compact surface-mount package suitable for modern electronic designs.

Replacement Considerations

The EK43602-01 is listed as a similar replacement kit, though it is an evaluation board rather than a direct component substitute. For direct component substitution, consult pSemi for updated part numbers within the same family, such as other variants in the PE436xx series, ensuring pin compatibility and electrical specifications match.
