HFA3664IA

Overview

The HFA3664IA is an RF upconverter integrated circuit manufactured by Harris Corporation. It operates within a frequency range of 2.3GHz to 2.7GHz and supports CDMA, TDMA, and WLAN applications. The device is housed in a 20-QSOP surface-mount package with a width of 3.90mm.

Feature Summary

• Designed for RF upconversion tasks in wireless communication systems
• Supports multiple modulation standards including CDMA, TDMA, and WLAN
• Utilizes a compact 20-pin QSOP surface-mount package

Applications

• CDMA wireless communication systems
• TDMA network infrastructure
• WLAN signal processing modules

Procurement Notes

Verify the manufacturer origin, as Harris Corporation's semiconductor assets were acquired by Intersil and subsequently Renesas. Ensure the component matches the original Harris specification sheet rather than generic equivalents. Confirm the 20-QSOP package dimensions and pinout compatibility with your PCB design before procurement.

Selection Notes

Select this component when designing systems requiring upconversion between 2.3GHz and 2.7GHz. It is suitable for applications supporting CDMA, TDMA, or WLAN protocols. Consider the surface-mount package constraints and ensure thermal management aligns with the QSOP form factor requirements for your specific board layout.

Part Context

Harris Corporation was a prominent American technology and defense contractor. This specific IC belongs to their RF miscellaneous components portfolio. The company has undergone significant corporate restructuring, with its semiconductor division becoming part of other entities, making original datasheets critical for accurate technical reference.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to corporate acquisitions involving Intersil and Renesas, verify if newer generations from these entities offer direct pin-compatible alternatives.
