D3C3740Q-2

RF Circulators And Isolators Overview

The D3C3740Q-2 is a single-junction RF circulator manufactured by DiTom Microwave, designed for the 37 GHz to 40 GHz frequency range. It features Type-N female connectors and operates within a temperature range of -20°C to +65°C. The component supports an average forward power of 5 W, with a maximum insertion loss of 0.7 dB and isolation of 18 dB. Voltage standing wave ratio (VSWR) is specified at 1.25. The device is housed in a module package measuring 0.5 inches by 0.5 inches by 0.7 inches.

RF Circulators And Isolators Feature Summary

• Provides non-reciprocal signal routing for three-port microwave applications
• Maintains low insertion loss across the designated Ka-band frequency spectrum
• Ensures high port-to-port isolation to minimize signal interference

RF Circulators And Isolators Applications

• Ka-band radar systems
• Point-to-point microwave communication links
• Satellite ground station transceivers

RF Circulators And Isolators Procurement Notes

Verify connector gender and interface type compatibility before integration. Confirm RoHS3 compliance status for environmental regulations. Check datasheet for precise thermal management requirements given the operating temperature limits. Ensure mechanical dimensions fit the intended PCB or chassis layout. Validate that the 5 W power rating aligns with system peak power levels.

RF Circulators And Isolators Selection Notes

Select this model when a three-port circulator is required for the 37-40 GHz band. Choose based on the need for Type-N female interfaces rather than other connector types. Consider the specific VSWR and isolation specifications against system sensitivity requirements. Evaluate the physical module size constraints for the assembly design.

RF Circulators And Isolators Part Context

This component belongs to the D3C3740Q series of RF circulators from DiTom Microwave. The series targets high-frequency microwave applications requiring reliable signal directionality. The part number suffix typically denotes specific connector configurations or performance variants within the family.

RF Circulators And Isolators Replacement Considerations

D3C3740Q-1: Offers identical frequency range and power handling but may differ in isolation or VSWR metrics. Verify connector configuration and electrical parameters match before substitution.
