PE43404MLI

Overview

The PE43404MLI is a digital step attenuator manufactured by pSemi, designed for RF applications up to 2 GHz. It provides a fixed attenuation value of 15 dB with a characteristic impedance of 75 Ohms. The device is housed in a 20-WFQFN package featuring an exposed pad for thermal management and ground connection. This component is part of the pSemi family of intelligent electronics, utilizing proprietary technology for signal conditioning.

Feature Summary

Provides precise 15 dB attenuation for signal level control
Operates with 75 Ohm system impedance compatibility
Supports frequencies up to 2 GHz
Utilizes compact 20-WFQFN surface-mount packaging

Applications

RF signal path attenuation
Test and measurement equipment
Wireless communication systems requiring 75 Ohm interfaces

Procurement Notes

Verify the specific suffix (e.g., -Z) against the manufacturer's current datasheet to confirm availability and exact specifications. Ensure the 20-WFQFN package dimensions align with PCB layout requirements. Confirm that the 75 Ohm impedance matches the system design before integration.

Selection Notes

Select this component when a fixed 15 dB attenuation is required in a 75 Ohm environment. Consider the 2 GHz frequency limit and the 20-WFQFN package size. Verify thermal performance needs due to the exposed pad design. Compare with variable attenuators if adjustable attenuation is necessary instead of a fixed value.

Part Context

This component belongs to pSemi's portfolio of RF and microwave integrated circuits. It complements other signal conditioning devices like switches and amplifiers. The 75 Ohm specification distinguishes it from standard 50 Ohm RF components, making it suitable for specific cable and broadcast standards.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consult the manufacturer's official cross-reference guide or datasheet for equivalent parts with matching 15 dB attenuation, 75 Ohm impedance, and 20-WFQFN packaging.
