PE43601MLI

Overview

The PE43601MLI is a high linearity, 6-bit RF Digital Step Attenuator (DSA) from pSemi. It provides a 15.75 dB attenuation range with a resolution of 0.25 dB per step. The device operates at a characteristic impedance of 50 Ohms and supports frequencies up to 3 GHz. It utilizes HaRP™ technology for enhanced performance. The component is housed in a 32-lead VFQFN package with an exposed pad, designed for surface mount installation.

Feature Summary

• Utilizes HaRP™ technology for high linearity performance
• Provides precise digital control over RF signal attenuation
• Features a compact 32-lead VFQFN package design

Applications

• RF signal processing systems
• Communication equipment requiring variable attenuation
• Test and measurement instrumentation

Procurement Notes

Verify the specific suffix of the part number during procurement, as the base model PE43601 may have variations. Confirm that the required version matches the 32-VFQFN package specification. Check current availability status, as some listings indicate this specific variant may be obsolete or discontinued, necessitating verification of stock levels or alternative sourcing channels before finalizing orders.

Selection Notes

Select the PE43601MLI when a 6-bit resolution with 0.25 dB steps is required within a 15.75 dB range. Ensure the application environment supports the 50 Ohm impedance standard. Consider the thermal requirements associated with the exposed pad VFQFN package. Verify that the operating frequency does not exceed the 3 GHz maximum limit specified for this component type.

Part Context

This component belongs to pSemi's UltraCMOS series of RF integrated circuits. It is categorized under wireless and RF integrated circuits, specifically digital step attenuators. The PE43601MLI represents a specialized solution for applications demanding high linearity and precise attenuation control in compact form factors compared to older generation attenuators.

Replacement Considerations

Public documentation indicates PE43712B-Z as a potential substitute for the PE43601MLI-Z variant. Verify compatibility regarding pinout, attenuation range, and package dimensions before implementing any replacement strategy.
