D3I9521N

RF Circulators And Isolators Overview

The D3I9521N is a single-junction RF isolator manufactured by DiTom Microwave, designed for operation within the 950 MHz to 2.15 GHz frequency range. This component features Type-N female connectors and supports an average forward power of 75 W. Key electrical specifications include an isolation of 12 dB, insertion loss of 1 dB, and a voltage standing wave ratio (VSWR) of 1.65. The device is housed in a module package with physical dimensions of 2.8 inches by 1 inch by 2.8 inches. It operates within a temperature range of -10°C to +55°C and complies with RoHS3 standards.

RF Circulators And Isolators Feature Summary

• Provides unidirectional signal transmission to protect source components from reflected power
• Utilizes a single-junction ferrite design for stable performance across the specified bandwidth
• Features robust mechanical construction suitable for demanding RF environments

RF Circulators And Isolators Applications

• Transmitter output stages for signal protection
• Receiver input stages to improve noise figure
• Bidirectional communication systems requiring signal separation

RF Circulators And Isolators Procurement Notes

Verify the specific suffix variant required, as DiTom Microwave offers multiple configurations such as D3I9521N-1, D3I9521N-2, and D3I9521N-3 which may differ in connector orientation or internal tuning. Confirm that the standard D3I9521N part number matches the exact electrical and mechanical requirements of the target circuit design before ordering.

RF Circulators And Isolators Selection Notes

Select this component when a wideband isolator covering 950 MHz to 2.15 GHz is required with moderate power handling capabilities. Ensure the system impedance matches the component's design impedance. Consider the physical footprint of 2.8 x 1 x 2.8 inches for adequate clearance in the assembly layout. Verify thermal management needs given the 75 W power rating and operating temperature limits.

RF Circulators And Isolators Part Context

This model belongs to the DiTom Microwave D3I9521N series of RF isolators. The series includes variants like D3I9521N-1, D3I9521N-2, and D3I9521N-3, which share similar core specifications but may have distinct packaging or connector details. The manufacturer specializes in thermal vacuum coaxial ferrite isolators for specialized applications.

RF Circulators And Isolators Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Evaluate other DiTom models within the D3I9521N family for potential compatibility. Cross-reference with generic wideband isolators ensuring identical frequency range, power handling, and connector type match.
