D4I0810N-3

RF Circulators And Isolators Overview

The D4I0810N-3 is an RF isolator manufactured by DiTom Microwave, designed for operation within the 800 MHz to 1 GHz frequency range. It features Type-N male connectors on both input and output ports, facilitating integration into standard coaxial systems. The component supports a maximum average forward power of 250 W and provides 40 dB of isolation. Key electrical performance metrics include a voltage standing wave ratio (VSWR) of 1.25 and insertion loss of 0.4 dB. Physically, it is housed in a module package with dimensions of 1.25 inches by 0.73 inches by 1.25 inches.

RF Circulators And Isolators Feature Summary

• Provides high isolation of 40 dB to protect source components from reflected signals
• Supports high average forward power handling up to 250 W
• Features low insertion loss of 0.4 dB for efficient signal transmission
• Maintains excellent impedance matching with a VSWR of 1.25

RF Circulators And Isolators Applications

• Protection of power amplifiers from load mismatches
• Test and measurement equipment operating in the UHF band
• Communication systems utilizing Type-N connector interfaces

RF Circulators And Isolators Procurement Notes

Verify the specific datasheet version for the D4I0810N-3 to confirm current manufacturing status and environmental compliance details. Ensure that the required connector configuration matches the Type-N male specification documented for this part number. Cross-reference the physical dimensions against your enclosure design constraints prior to ordering. Confirm RoHS3 compliance requirements align with your project regulations.

RF Circulators And Isolators Selection Notes

Select the D4I0810N-3 when a single-junction isolator is required for the 800 MHz to 1 GHz band. This model is suitable for applications demanding 250 W power handling and 40 dB isolation. Compare its 1.25-inch module size against space-constrained alternatives if necessary. Ensure system impedance matches the component's design parameters for optimal VSWR performance.

RF Circulators And Isolators Part Context

This component belongs to the DiTom Microwave RF isolator and circulator product line. It shares the same operational frequency range and general form factor characteristics as other models in the series, such as the D3I0810N-3. However, the D4I0810N-3 is specifically configured as an isolator rather than a circulator, distinguishing its functional application in signal routing versus protection.

RF Circulators And Isolators Replacement Considerations

The D3I0810N-3 is a related model within the same manufacturer's lineup, sharing the 800 MHz to 1 GHz frequency range and similar physical dimensions. While both operate in the same band, the D3C0810N-3 is a circulator, whereas the D4I0810N-3 is an isolator; verify functional compatibility before substitution.
