D3C9517N-1

RF Circulators And Isolators Overview

The D3C9517N-1 is a three-port RF circulator manufactured by DiTom Microwave, designed for operation within the 950 MHz to 1.7 GHz frequency range. It features Type-N female connectors on all ports and utilizes a single junction configuration housed in a module package. The component supports an average forward power of 75 W, with a maximum insertion loss of 0.5 dB and isolation of 18 dB. Voltage Standing Wave Ratio (VSWR) is specified at 1.3. It operates between +10°C and +55°C and complies with RoHS3 standards.

RF Circulators And Isolators Feature Summary

• Provides non-reciprocal signal routing across a wide UHF bandwidth using a single junction design.
• Ensures high port-to-port isolation to minimize signal interference in multi-directional transmission paths.
• Supports substantial average forward power handling suitable for demanding RF applications.

RF Circulators And Isolators Applications

• Transmitter-receiver separation in communication systems
• Duplexer implementation in radar systems
• Signal routing in microwave test and measurement equipment

RF Circulators And Isolators Procurement Notes

Verify connector gender and interface compatibility before integration. Confirm thermal management requirements for continuous 75 W operation. Check RoHS3 compliance documentation for regulatory adherence. Ensure operating temperature limits are respected in the final assembly environment.

RF Circulators And Isolators Selection Notes

Select this model when a three-port non-reciprocal device is required for the 950 MHz to 1.7 GHz band. Consider the 75 W power rating and 18 dB isolation as key performance indicators. Verify that Type-N female connectors match the system interconnect strategy.

RF Circulators And Isolators Part Context

This part belongs to the D3C9517 series of RF circulators from DiTom Microwave. Variants such as D3C9517N-3 and D3C9517N-5 offer different connector configurations while maintaining similar electrical specifications. The D3C9517N-1 specifically denotes the Type-N female configuration.

RF Circulators And Isolators Replacement Considerations

Direct substitutes include other D3C9517 series variants like D3C9517N-3 or D3C9517N-5 if connector differences are acceptable. Cross-manufacturer replacements require matching frequency, power, and isolation specs.
