PE46120A-X

Overview

The PE46120A-X is a monolithic phase and amplitude controller (MPAC) utilizing HaRP™ technology, designed for precise control of two RF channels. It operates within the 1.8 GHz to 2.2 GHz frequency range. The device integrates a 5-bit digital phase shifters and a 4-bit digital step attenuator on a single chip. It is housed in a 32-QFN (6x6 mm) surface-mount package with an exposed pad for thermal management.

Feature Summary

• Integrates 5-bit digital phase shifting and 4-bit digital step attenuation capabilities
• Utilizes HaRP™ technology for enhanced performance
• Provides simultaneous phase and amplitude control for dual RF channels

Applications

• Phased array antenna systems
• Beamforming networks
• RF signal processing modules

Procurement Notes

Verify component status as the PE46120A-X is listed as obsolete by the manufacturer. Confirm availability through authorized distributors or secondary market sources. Ensure compatibility with existing design infrastructure before procurement planning. Check for valid replacement part numbers if new production is required.

Selection Notes

Select this component for applications requiring integrated phase and amplitude control in the 1.8-2.2 GHz band. Consider the 32-QFN package constraints for PCB layout. Evaluate thermal requirements due to the exposed pad design. Verify that the digital control interface matches system logic levels.

Part Context

This MPAC belongs to pSemi's portfolio of RF control solutions. It differs from other models like the PE46140A-X primarily in operational frequency and specific bit configurations. The device represents a specialized solution for high-frequency beamforming applications rather than general-purpose switching.

Replacement Considerations

Public confirmed substitute part numbers are not explicitly documented in the provided source material. Consult manufacturer documentation for direct replacements or evaluate equivalent MPACs with similar 5-bit/4-bit configurations.
