D4C9211-1

RF Circulators And Isolators Overview

The D4C9211-1 is a microwave circulator manufactured by DiTom Microwave, designed for operation within the 9.2 GHz to 10.5 GHz frequency range. This component utilizes SMA female connectors and is housed in a module package. It supports an average forward power of 10 W with a maximum isolation of 23 dB. Key electrical specifications include an insertion loss of 0.3 dB and a Voltage Standing Wave Ratio (VSWR) of 1.2. The device complies with RoHS3 standards and carries an ECCN classification of EAR99.

RF Circulators And Isolators Feature Summary

• Provides directional signal routing via three-port circulation within the specified Ku-band frequency range
• Maintains low signal attenuation through optimized internal magnetic circuit design
• Ensures impedance matching stability with minimal reflection characteristics
• Facilitates integration into compact RF systems using standard SMA interface connections

RF Circulators And Isolators Applications

• Transmitter-receiver switching in radar systems
• Duplexing in communication transceivers
• Signal routing in test and measurement equipment
• Isolation stages in microwave amplifier chains

RF Circulators And Isolators Procurement Notes

Verify that the specific part number D4C9211-1 matches the required frequency band and connector type for your system design. Confirm compliance with environmental regulations such as RoHS3 if applicable to your region. Check the manufacturer's current datasheet for any updates on mechanical dimensions or thermal handling requirements before finalizing the procurement order.

RF Circulators And Isolators Selection Notes

Select this component when a three-port circulator is needed for the 9.2–10.5 GHz range with SMA connectivity. Ensure the system can handle the 10 W average power limit. Compare against isolator variants like D3I9211-1 if unidirectional transmission is sufficient, noting that circulators allow bidirectional flow between ports while isolators restrict it to one direction.
