D3I1922-1

RF Circulators And Isolators Overview

The D3I1922-1 is a single-junction RF isolator manufactured by DiTom Microwave, designed for operation within the 19 GHz to 22 GHz frequency range. It features SMA-Female connectors and utilizes a module package configuration. The component supports an average forward power of 10 W while maintaining an isolation level of 22 dB. Key electrical performance metrics include a maximum insertion loss of 0.4 dB and a voltage standing wave ratio (VSWR) of 1.2. The device operates reliably within a temperature range of -20°C to +65°C and complies with RoHS3 standards.

RF Circulators And Isolators Feature Summary

• Provides unidirectional signal transmission to protect source components from reflected power in microwave circuits.
• Utilizes a single-junction design to achieve high isolation performance across the specified Ku-band frequency range.
• Integrates SMA-Female connectors for direct interfacing with standard coaxial test and measurement equipment.

RF Circulators And Isolators Applications

• Microwave communication systems requiring signal directionality
• Test and measurement instrumentation setups
• Satellite ground station receiver chains

RF Circulators And Isolators Procurement Notes

Verify the specific connector gender and mechanical dimensions against system requirements before ordering. Confirm that the 10 W power rating aligns with peak and average power levels in the target application. Ensure compatibility with the -20°C to +65°C operating temperature range. Check for any specific handling instructions related to the SMA interface integrity during installation.

RF Circulators And Isolators Selection Notes

Select this model when a compact isolator is needed for the 19-22 GHz band with moderate power handling. Compare insertion loss and VSWR specifications against other available options to ensure minimal signal degradation. Consider the physical module size relative to the available PCB or chassis space. Evaluate the thermal management capabilities if the device will operate continuously near its maximum temperature limit.

RF Circulators And Isolators Part Context
