D4I0118-3

RF Circulators And Isolators Overview

The DiTom Microwave D4I0118-3 is an RF isolator operating within the 1.60 to 1.80 GHz frequency range. It features SMA female connectors and supports an average forward power of 150 W. Key electrical specifications include a maximum insertion loss of 0.8 dB, an isolation rating of 40 dB, and a voltage standing wave ratio (VSWR) of 1.25. The device operates between -20°C and +65°C and is housed in a module package with SMA connectors.

RF Circulators And Isolators Feature Summary

• Provides directional signal protection by allowing transmission in one direction while attenuating reverse signals.
• Maintains high signal integrity through low insertion loss and stable impedance matching characteristics.
• Handles significant average forward power levels suitable for robust RF system applications.

RF Circulators And Isolators Applications

• RF wireless communication systems requiring signal directionality
• L-band frequency range transmitter output protection
• High-frequency circuit isolation to prevent source reflection interference

RF Circulators And Isolators Procurement Notes

Verify the specific manufacturer part number D4I0118-3 against official DiTom Microwave documentation to confirm current availability and lead times. Ensure that the SMA female connector configuration matches your system interface requirements. Check RoHS compliance status and environmental operating temperature limits (-20°C to +65°C) for your specific deployment conditions before finalizing procurement orders.

RF Circulators And Isolators Selection Notes

Select this component when a 1.60–1.80 GHz isolator with 150 W power handling is required. Confirm that the 40 dB isolation level meets your system's noise floor and reflection management needs. Verify that the SMA female interface is compatible with existing cabling and fixture designs. Consider the physical module dimensions and thermal management capabilities relative to your enclosure constraints.

RF Circulators And Isolators Part Context

This model belongs to the DiTom Microwave series of RF isolators designed for L-band applications. It serves as a passive component to protect sensitive sources from reflected power. The D4I0118-3 variant specifically denotes the SMA female connector configuration within the broader D4I0118 product family, ensuring standardized interfacing for modular RF setups.

RF Circulators And Isolators Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. When evaluating alternatives, ensure the replacement matches the 1.60–1.80 GHz frequency range, 150 W power rating, and SMA female connector type. Verify that equivalent isolation and VSWR specifications are met to maintain system performance integrity.
