D3I1722S-3

RF Circulators And Isolators Overview

The D3I1722S-3 is a single junction RF isolator manufactured by DiTom Microwave, designed for operation within the 1.7 GHz to 2.2 GHz frequency range. It utilizes SMA female connectors and is housed in a module package. Key electrical specifications include an average forward power rating of 10 W, isolation of 20 dB, insertion loss of 0.4 dB, and a voltage standing wave ratio (VSWR) of 1.25.

RF Circulators And Isolators Feature Summary

• Provides signal isolation in the 1.7 to 2.2 GHz band using a single junction design.
• Features SMA female coaxial connectors for standard interface compatibility.
• Operates reliably within a temperature range of -20°C to +65°C.

RF Circulators And Isolators Applications

• RF signal path protection in communication systems
• Transmitter output stages requiring reverse power isolation
• Test and measurement equipment setups

RF Circulators And Isolators Procurement Notes

Verify the specific suffix '-3' against the manufacturer's current documentation to confirm connector configuration and mechanical dimensions. Ensure that the SMA female interface matches system requirements. Confirm RoHS3 compliance status if environmental regulations apply to the final assembly. Cross-reference the part number with official DiTom Microwave datasheets to validate all electrical parameters before integration.

RF Circulators And Isolators Selection Notes

Select this component when a 10 W power handling capability and 20 dB isolation are required in the S-band or C-band applications. The SMA female interface dictates mating cable or fixture types. Consider the physical dimensions of 1.25 in x 0.73 in x 1.25 in for board layout clearance. Evaluate thermal management needs based on the 10 W average power rating and operating temperature limits.

RF Circulators And Isolators Part Context

This model belongs to the DiTom Microwave series of RF circulators and isolators. It is categorized under RF accessories and filters. The product is identified as a single junction isolator, distinct from multi-junction variants. It shares the base D3I1722 designation but differs in connector type and packaging specifics defined by the suffix.

RF Circulators And Isolators Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Verify compatibility with existing designs by matching the 1.7-2.2 GHz frequency range, SMA female interface, and 10 W power rating. Consult DiTom Microwave directly for alternative models with similar electrical performance characteristics.
