HFA3101BZ

RF Mixers Overview

The HFA3101BZ is a high-performance RF mixer integrated circuit manufactured by Renesas Electronics Corporation. It operates within a frequency range of 0Hz to 10GHz and features a noise figure of 1.7dB. The device is housed in an 8-SOIC surface-mount package with a width of 3.90mm. This component is currently listed as obsolete or discontinued.

RF Mixers Feature Summary

• Configured as a Gilbert Cell multiplier using an all-NPN transistor array
• Utilizes Intersil bonded wafer UHF-1 SOI process technology for high-frequency performance

RF Mixers Applications

• UHF radio frequency mixing applications
• Multiplier cell implementations in RF circuits

RF Mixers Procurement Notes

Verify the obsolete status of the HFA3101BZ before initiating any procurement activities. As the component is discontinued, availability may be limited to surplus stock. Ensure that any sourced units are authentic and meet original specifications, as replacement sourcing requires careful validation of part authenticity and condition.

RF Mixers Selection Notes

Select this component only if the specific 0Hz-10GHz frequency range and 1.7dB noise figure align with system requirements. Consider the 8-SOIC package constraints for PCB layout. Due to its discontinued status, evaluate alternative modern RF mixers with comparable performance metrics and longer lifecycle support for new designs.

RF Mixers Part Context

The HFA3101BZ belongs to the HFA3101 series of RF mixers. It is based on Intersil's bonded wafer UHF-1 SOI process, which was later integrated into Renesas Electronics' portfolio. The device represents a specialized NPN transistor array designed for high-frequency multiplier applications.

RF Mixers Replacement Considerations

No public confirmed substitute part numbers are available for the HFA3101BZ due to its discontinued status. Designers should consult official Renesas documentation for potential legacy replacements or modern equivalents.
