NCR2-123+

Balun Overview

The NCR2-123+ is a space-qualified ceramic RF balun from Mini-Circuits, designed for microwave applications. It operates within a frequency range of 4700 to 12000 MHz and features an insertion loss between 0.5 and 2.7 dB. The component utilizes a 1:2 impedance ratio and is housed in a compact 6-SMD, no-lead surface mount package.

Balun Feature Summary

• Space-qualified construction suitable for aerospace environments
• Ultra-wideband operation covering 4.7 to 12 GHz
• Compact surface mount design for high-density integration

Balun Applications

• Satellite communication systems
• Spaceborne radar equipment
• Microwave signal conditioning circuits

Balun Procurement Notes

Verify the specific space qualification status and environmental testing data required for your mission profile before procurement. Confirm that the 6-SMD package dimensions align with your PCB layout constraints. Ensure the supplier provides traceability documentation consistent with aerospace standards.

Balun Selection Notes

Select this component when a robust, space-rated balun is required for frequencies up to 12 GHz. Consider the 1:2 impedance transformation capability and the low insertion loss characteristics. Evaluate the thermal performance and physical size against your system's power and space limitations.

Balun Part Context

This part belongs to the Mini-Circuits NCR2 family of ultra-wideband balun transformers. While the broader family spans 3.5 to 18 GHz, the NCR2-123+ specifically targets the 4.7 to 12 GHz band. These components are engineered for high reliability in demanding RF environments.
