D4I8012Y-2

RF Circulators And Isolators Overview

The D4I8012Y-2 is a cryogenic RF isolator manufactured by DiTom Microwave, designed for operation within the 8.00 to 12.00 GHz frequency band. It features SMA female and male connectors with gold-plated copper contacts and a passivated stainless steel body. The component provides 40 dB of isolation, 1 dB of insertion loss, and supports an average forward power rating of 25 W. Its physical dimensions are 1.72 inches in length, 0.98 inches in width, and 0.5 inches in height.

RF Circulators And Isolators Feature Summary

• Cryogenic design optimized for low-temperature environments
• Dual SMA connector configuration for flexible integration
• High isolation performance of 40 dB
• Robust construction using passivated stainless steel

RF Circulators And Isolators Applications

• X-band microwave systems
• Cryogenic RF signal processing
• Low-noise amplifier protection

RF Circulators And Isolators Procurement Notes

Verify current availability status as the product lifecycle may be discontinued or limited. Confirm specific cryogenic temperature requirements against datasheet specifications before ordering. Ensure connector gender compatibility (SMA Female/Male) matches system interface needs. Check RoHS compliance details if environmental regulations apply to the deployment environment.

RF Circulators And Isolators Selection Notes

Select this component when operating frequencies strictly fall between 8.00 and 12.00 GHz. Consider the 25 W power handling capability relative to system peak levels. Evaluate the need for cryogenic operation versus standard ambient temperature alternatives like the D4I8012 series. Verify that the SMA connector types align with existing cable assemblies and test equipment interfaces.

RF Circulators And Isolators Part Context

This model belongs to the DiTom Microwave D4I8012 family of isolators. While similar models like the D4I8012 operate up to 12.40 GHz, the Y-2 variant is specifically tuned for the 8.00–12.00 GHz range. It shares structural similarities with other variants but differs in frequency coverage and connector configuration, distinguishing it from standard non-cryogenic versions.

RF Circulators And Isolators Replacement Considerations

The D4I8012-1 serves as a related alternative with a slightly extended upper frequency limit of 12.40 GHz. However, verify if the standard ambient version meets thermal requirements instead of the cryogenic specification. Cross-reference connector genders carefully, as the D4I8012-1 typically utilizes SMA-Female configurations only.
