ISL5239KIZ

Overview

The ISL5239KIZ is a pre-distortion linearizer manufactured by Renesas Electronics, designed for RF applications including CDMA2000 and UMTS systems. It utilizes a 196-BGA (15x15) package style to provide mechanical and thermal protection. The component functions as part of the ISL5239 family, addressing linearity requirements in wireless communication transmitters.

Feature Summary

• Provides pre-distortion linearization for RF power amplifiers
• Supports CDMA2000 and UMTS radio frequency standards
• Housed in a 196-ball BGA package for thermal management

Applications

• CDMA2000 base station transmitter systems
• UMTS cellular infrastructure equipment
• RF power amplifier linearization modules

Procurement Notes

Verify component status carefully as this specific part number is listed as obsolete. Confirm availability through authorized distributors or secondary market suppliers. Ensure compatibility with existing evaluation boards such as the ISL5239EVAL1 if testing is required. Check datasheet revisions for any final design-in recommendations before procurement.

Selection Notes

Select this component only for legacy designs requiring CDMA2000 or UMTS linearization. Consider modern alternatives if designing new hardware due to obsolete status. Evaluate thermal performance within the 196-BGA footprint against system constraints. Verify signal integrity requirements match the linearizer's specifications.

Part Context

The ISL5239KIZ belongs to the ISL5239 family of pre-distortion linearizers. It is distinct from Renesas microcontroller lines like the RX series. The KIZ suffix denotes the specific 196-BGA package variant. This component addresses historical wireless communication standards rather than current IoT or Bluetooth protocols.
