MMW9004KCZ

Overview

The MMW9004KCZ is a general-purpose RF transmitter integrated circuit manufactured by NXP USA Inc. It operates within the frequency range of 24.25GHz to 27.5GHz. The device features a 4-channel analog beamforming architecture, designed for precise signal directionality in millimeter-wave applications. It utilizes an SPI interface for configuration and control. The component is packaged in a 56-WLCSP with dimensions of 4.39x3.59 mm. The part status is designated as Not For New Designs.

Feature Summary

• Integrates four-channel analog beamforming capabilities for directional signal transmission
• Operates within the 24.25GHz to 27.5GHz millimeter-wave frequency spectrum
• Supports digital control via Serial Peripheral Interface (SPI)
• Utilizes a compact 56-WLCSP surface mount package

Applications

• General-purpose RF transmitter systems
• Millimeter-wave communication links
• Beamforming antenna arrays
• Short-range high-frequency data transmission

Procurement Notes

Verify that the MMW9004KCZ is suitable for legacy or maintenance projects, as it is explicitly marked as Not For New Designs. Confirm availability through authorized distributors, noting that supply may be limited due to end-of-life status. Ensure compatibility with existing system architectures before procurement, as no new design implementations are recommended for this component.

Selection Notes

Select this component only for applications requiring 4-channel analog beamforming in the 24-27.5GHz range. Consider the WLCSP package size constraints and SPI interface requirements. Evaluate alternative active components if new product development is intended, given the Not For New Designs status. Verify thermal and electrical compatibility with host PCB designs.

Part Context

The MMW9004KCZ belongs to NXP's portfolio of RF miscellaneous ICs and modules. It serves as a specialized transmitter solution for millimeter-wave frequencies. The component is distinct from broader RF families by its specific focus on analog beamforming integration within a single transmitter chip, targeting niche high-frequency communication needs.

Replacement Considerations

No public confirmed substitute part numbers are available. Due to the Not For New Designs status, direct replacements may require redesigning the RF front-end. Consult NXP technical support for potential obsolescence management options or long-term supply agreements.
