PE43502MLI

Overview

The PE43502MLI is a monolithic RF attenuator utilizing UltraCMOS technology. It provides a fixed attenuation value of 15.5 dB with a characteristic impedance of 50 ohms. The device operates within a frequency range of 9 kHz to several GHz, ensuring stable performance across wide bandwidths. Packaged in a 24-VFQFN exposed pad format, it integrates high-reliability semiconductor design for consistent signal control in radio frequency applications.

Feature Summary

• Utilizes UltraCMOS technology for enhanced reliability and integration
• Provides fixed 15.5 dB attenuation with 50-ohm impedance matching
• Operates from 9 kHz up to multi-GHz frequencies
• Compact 24-VFQFN package with exposed pad for thermal management

Applications

• RF signal conditioning in wireless infrastructure
• Test and measurement equipment calibration
• Radio frequency front-end module adjustment
• Communication system gain control

Procurement Notes

Verify the complete part number including the suffix 'MLI' to ensure correct packaging and tape-and-reel configuration. Confirm RoHS compliance status as per current manufacturer specifications. Cross-reference the datasheet for absolute maximum ratings and thermal dissipation requirements before integration into final designs.

Selection Notes

Select this component when a precise, fixed attenuation value is required rather than variable control. Consider the 24-VFQFN footprint for space-constrained PCB layouts. Ensure the operating frequency range aligns with the specific application bandwidth needs. Evaluate thermal performance characteristics given the exposed pad design for effective heat dissipation during continuous operation.

Part Context

This component belongs to the general-purpose RF digital step attenuator family produced by pSemi, a Murata company. It builds upon Peregrine Semiconductor's legacy in RF CMOS technology.
