D3C3783

RF Circulators And Isolators Overview

The DiTom Microwave D3C3783 is a three-port RF circulator designed for the 3.7 GHz to 8.3 GHz frequency range. It features SMA-Female connectors and operates within a temperature range of 0°C to +50°C. The component supports an average forward power of 20 W and a peak power of 30 W. Key electrical specifications include an insertion loss of 0.5 dB, isolation of 18 dB, and a VSWR of 1.3. The device utilizes a single junction design and is housed in a module package measuring 1 inch by 0.5 inches by 1 inch.

RF Circulators And Isolators Feature Summary

• Provides non-reciprocal signal routing across a wide microwave frequency band using a single junction architecture.
• Integrates SMA-Female connectors for standardized interface compatibility in RF systems.
• Supports high average forward power handling suitable for demanding transmission applications.

RF Circulators And Isolators Applications

• RF and wireless communication systems
• Quantum computing applications requiring cryogenic operation compatibility
• Microwave circuit isolation and signal direction control

RF Circulators And Isolators Procurement Notes

Verify that the specific suffix variant matches the required connector configuration or performance tolerance, as ordering suffixes may denote physical or electrical differences. Confirm RoHS3 compliance status if environmental regulations apply to the final assembly. Ensure the operating temperature range aligns with the system's thermal environment, as the standard range is specified from 0°C to +50°C.

RF Circulators And Isolators Selection Notes

Select this component when a wide bandwidth circulator is needed between 3.7 GHz and 8.3 GHz. Consider the 20 W average power rating for system power budgeting. The SMA-Female interface dictates the necessary cable or fixture connections. Verify that the 18 dB isolation level meets the system's interference rejection requirements.

RF Circulators And Isolators Part Context

The D3C3783 belongs to the DiTom Microwave D3C series of RF circulators. This family includes variants such as D3C3783-1 through D3C3783-7, which share the core frequency and power specifications but may differ in connector types or mechanical configurations. The series is noted for suitability in quantum computing environments due to cryogenic operational capabilities.

RF Circulators And Isolators Replacement Considerations

Direct substitutes within the same series include part numbers D3C3783-1, D3C3783-2, D3C3783-6, and D3C3783-7. These alternatives maintain the 3.7–8.3 GHz frequency range and 20 W power rating but may feature different connector arrangements or packaging details. Cross-reference datasheets to ensure mechanical fit and interface compatibility before substitution.
