D3I1525-3

RF Circulators And Isolators Overview

The D3I1525-3 is a single-junction RF isolator manufactured by DiTom Microwave, designed for operation within the 1.5 GHz to 2.5 GHz frequency range. It features SMA female connectors on both ports and operates at an average forward power of 50 W. Key electrical specifications include an insertion loss of 0.6 dB, an isolation rating of 16 dB, and a voltage standing wave ratio (VSWR) of 1.4. The device functions within a temperature range of +10°C to +55°C and is housed in a module package measuring 2.5 inches by 0.55 inches by 2.5 inches.

RF Circulators And Isolators Feature Summary

• Provides unidirectional signal transmission with high isolation characteristics
• Operates as a single-junction component for stable RF performance
• Utilizes SMA female connectors for standard interface compatibility

RF Circulators And Isolators Applications

• RF signal path protection in communication systems
• Transmitter output isolation to prevent reflected power damage
• Receiver input protection against source reflections

RF Circulators And Isolators Procurement Notes

Verify the specific datasheet version for the D3I1525-3 to confirm current RoHS compliance status and detailed electrical tolerances. Ensure that the SMA female connector configuration matches the system requirements. Confirm availability through authorized distributors, as supply status may vary. Cross-reference the operating temperature limits with the intended environmental conditions to ensure reliable performance.

RF Circulators And Isolators Selection Notes

Select this component when a 1.5 GHz to 2.5 GHz isolator is required with 50 W power handling capability. The 16 dB isolation and 0.6 dB insertion loss meet standard RF circuit requirements. Verify that the physical dimensions fit the assembly space. Ensure the SMA female interface aligns with existing cabling and fixture designs. Consider the operating temperature range for thermal management planning.

RF Circulators And Isolators Part Context

This part belongs to the DiTom Microwave D3I series of RF isolators and circulators. It shares the same frequency band and connector type with other models in the family but differs in internal junction design and specific electrical parameters. The D3I1525-3 is distinct from circulator variants like the D3C1525-3, which offer multi-port functionality rather than two-port isolation.

RF Circulators And Isolators Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Users must verify compatibility with alternative components based on matching frequency, power, and connector specifications.
