NCR2-113+

Balun Overview

The NCR2-113+ is a space-qualified RF balun transformer manufactured by Mini-Circuits. It operates within a frequency range of 3.5 GHz to 11 GHz, providing a bandwidth of 7500 MHz. The component features a 1:2 impedance ratio and is designed for 50 Ohm systems. It utilizes an SMD/SMT termination style in a 6-SMD, No Lead package. The device exhibits an amplitude unbalance of +/- 1.0 dB across its operational spectrum.

Balun Feature Summary

• Space-qualified reliability for aerospace applications
• Ultra-wideband operation from 3.5 GHz to 11 GHz
• 1:2 impedance transformation ratio
• Compact surface-mount LTCC construction

Balun Applications

• Satellite communication systems
• Space-qualified radar transceivers
• Wideband balanced-to-unbalanced signal conversion
• High-frequency microwave circuit interfaces

Balun Procurement Notes

Verify the specific space-qualification certification level required for your mission profile before ordering. Confirm that the 1:2 impedance ratio aligns with your system's differential and single-ended interface requirements. Ensure the 6-SMD no-lead package dimensions fit within your PCB layout constraints. Cross-reference the amplitude unbalance specifications against your link budget calculations to guarantee signal integrity.

Balun Selection Notes

Select this component when wideband coverage between 3.5 GHz and 11 GHz is mandatory. Choose the NCR2-113+ over other variants if space qualification is a strict requirement. Consider the 1:2 ratio specifically for driving differential loads from single-ended sources. Evaluate thermal management needs as the LTCC structure impacts heat dissipation characteristics compared to wire-wound alternatives.

Balun Part Context

This part belongs to the NCR2 family of ultra-wideband balun transformers from Mini-Circuits. The series covers frequencies up to 18 GHz, with the NCR2-113+ focusing on the lower segment of this range. It is distinct from standard commercial baluns due to its enhanced radiation hardness and vacuum compatibility suitable for orbital deployment.

Balun Replacement Considerations

No direct public substitute part numbers are confirmed for this specific space-qualified variant. Alternative NCR2 models may offer different frequency ranges but lack identical qualification status.
