PE43702MLI

Overview

The PE43702MLI is a 50-ohm RF digital step attenuator from the UltraCMOS family. It provides 7-bit resolution with a total attenuation range of 31.75 dB in 0.5 dB steps. The device operates across a frequency range of DC to 4 GHz. It utilizes a serial control interface for configuration and is housed in a 24-VFQFN package with an exposed pad.

Feature Summary

• UltraCMOS technology enables high linearity and low power consumption
• Serial control interface simplifies system integration
• Precise 0.5 dB step resolution ensures accurate signal adjustment

Applications

• Wireless infrastructure base stations
• Test and measurement equipment
• Point-to-point microwave radio systems

Procurement Notes

Verify the specific ordering code suffix, as PE43702MLI-Z indicates RoHS compliance. Confirm package availability and lead times directly with authorized distributors or pSemi. Ensure the procurement channel is authorized to guarantee component authenticity and traceability.

Selection Notes

Select this model when a wide bandwidth up to 4 GHz is required alongside precise digital control. The 7-bit resolution offers fine granularity for gain management. Consider the 24-VFQFN package constraints for PCB layout and thermal dissipation requirements during design.

Part Context

This component belongs to the PE43702 series of RF digital attenuators manufactured by pSemi (formerly Peregrine Semiconductor). It is part of the UltraCMOS product line, which integrates GaN-on-SiC technology for superior performance compared to traditional silicon-based solutions.

Replacement Considerations

Direct substitutes include other models within the PE43702 series such as PE43702MLI. Verify pin compatibility and electrical specifications before substituting with generic RF attenuators.
