Procurement Notes

Verify the specific suffix GR2 against official Infineon documentation to confirm exact tape-and-reel specifications and packaging details. Ensure compatibility with existing PCB footprints for the SOT-23-3 package. Confirm that the hyperabrupt junction characteristics meet the precise linearity requirements of the target RF application before finalizing procurement.

Selection Notes

Select this component when a high tuning ratio and linear frequency response are required in space-constrained designs. The common-cathode arrangement simplifies circuit topology compared to discrete single diodes. Consider the 18 V reverse voltage limit and thermal management capabilities when designing for high-power or high-temperature environments.

Part Context

This part belongs to Infineon's portfolio of variable capacitance diodes, specifically utilizing hyperabrupt junction technology. It serves as a critical passive component in RF front-end modules, enabling precise frequency control in wireless communication systems where stable performance across varying temperatures is essential.

Replacement Considerations

Consult official Infineon cross-reference guides for verified substitutes. Generic varactor replacements may not match the specific hyperabrupt capacitance-voltage curve or the dual common-cathode configuration, potentially altering circuit performance.
