HFA3767IA

Overview

The HFA3767IA is an RF quadrature modulator designed for cellular communication systems, specifically supporting AMPS and CDMA standards. It operates at a center frequency of 130MHz, facilitating up-conversion tasks within radio transmitters. The component is housed in a compact 20-pin SSOP package with a width of 3.90mm (0.154 inches), optimizing board space for mobile device applications. This integrated circuit enables precise signal modulation required for analog and code-division multiple access protocols.

Feature Summary

• Supports AMPS and CDMA cellular modulation standards
• Integrated quadrature modulation functionality
• Optimized for 130MHz up-conversion operations

Applications

• AMPS cellular telephone transmitters
• CDMA mobile communication devices
• RF up-conversion modules in wireless handsets

Procurement Notes

Verify the manufacturer designation as Harris Corporation or its successor entities, noting that Harris Corporation's semiconductor division was acquired by Intersil and subsequently by Renesas Electronics. Confirm the package type matches the 20-pin SSOP specification. Ensure compliance with RoHS directives if required for modern manufacturing processes. Cross-reference part numbers carefully due to corporate restructuring history.

Selection Notes

Select this component when designing transmitters for legacy AMPS or CDMA networks requiring a 130MHz intermediate frequency stage. The choice depends on the need for integrated quadrature modulation in a small form factor. Consider the availability of successors from Renesas if original Harris stock is exhausted. Evaluate thermal and electrical requirements against the specific transmitter architecture.

Part Context

Harris Corporation was a prominent American technology company and defense contractor known for wireless equipment and IT services. The semiconductor division, which produced this RF IC, underwent significant corporate changes, including acquisition by Intersil and later Renesas Electronics. This historical context is relevant for tracing component lineage and sourcing authentic documentation from current manufacturers.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided data. Due to the acquisition of Harris Semiconductor by Intersil and then Renesas, consult Renesas Electronics for potential direct replacements or updated equivalents compatible with AMPS/CDMA 130MHz applications.
