D3I3740Q-2

RF Circulators And Isolators Overview

The DiTom Microwave D3I3740Q-2 is a single-junction RF isolator operating within the 37 GHz to 40 GHz frequency band. It features Type-K female connectors and is housed in a module package with dimensions of 0.5 inches by 0.5 inches by 0.7 inches. The component supports an average forward power of 5 W, providing 18 dB of isolation. Key electrical specifications include a maximum insertion loss of 0.7 dB and a voltage standing wave ratio (VSWR) of 1.3. The device functions reliably across a temperature range from -20°C to +65°C.

RF Circulators And Isolators Feature Summary

• Provides directional signal transmission with high isolation in the millimeter-wave spectrum
• Utilizes Type-K female connectors for secure interface integration
• Engineered as a single-junction ferrite device for stable performance

RF Circulators And Isolators Applications

• Millimeter-wave communication systems
• Test and measurement instrumentation
• Satellite ground station equipment

RF Circulators And Isolators Procurement Notes

Verify that the specific suffix Q-2 corresponds to the required connector configuration and packaging format before ordering. Confirm that the Type-K female interface matches the system design requirements. Ensure the operating environment remains within the specified -20°C to +65°C thermal limits. Check RoHS3 compliance status if environmental regulations apply to the project. Validate that the 5 W power rating aligns with the application's signal levels.

RF Circulators And Isolators Selection Notes

Select this model when a dedicated isolator is required rather than a circulator, as it offers two-port functionality. Consider the Type-K connector size relative to available board space and mating hardware. Evaluate the 18 dB isolation level against system noise floor requirements. Compare the 0.7 dB insertion loss impact on overall link budget efficiency. Assess the module form factor for ease of mechanical mounting in the assembly.

RF Circulators And Isolators Part Context

This component belongs to the DiTom Microwave series of connectorized ferrite devices designed for commercial applications. The manufacturer specializes in high-quality isolators and circulators ranging from 400 MHz to 43.5 GHz. The D3I3740Q-2 represents a specific variant optimized for the 37-40 GHz band, distinct from other models like the D3C3740Q-2 which serves as a circulator.
