NCS2-622+

Overview

The NCS2-622+ is a surface-mount RF balun manufactured by Mini-Circuits, designed for high-frequency signal conversion. It operates within a frequency range of 5.6 GHz to 6.2 GHz, providing a bandwidth of 600 MHz centered at 5.9 GHz. The component features a 1:2 impedance transformation ratio and maintains a nominal 50 Ohm system impedance. Key electrical specifications include a maximum insertion loss of 1.0 dB, a minimum return loss of 13.7 dB, and a phase difference of 6°. It is housed in a compact 6-SMD, no-lead package suitable for board mounting.

Feature Summary

• Converts single-ended signals to balanced differential signals using LTCC technology
• Provides precise amplitude and phase balance for high-frequency applications
• Designed for space-qualified environments with robust ceramic construction

Applications

• Space-qualified RF communication systems
• Satellite transceiver front-ends
• High-frequency balanced mixer circuits

Procurement Notes

Verify the specific ordering suffix and packaging configuration required for your production line, as availability may vary between cut tape and reel formats. Confirm that the RoHS exemption status aligns with your environmental compliance requirements. Ensure the lead time accounts for the manufacturer's standard delivery period, which may extend beyond immediate stock availability. Cross-reference the datasheet version to confirm material qualifications.

Selection Notes

Select this component when a 1:2 impedance transformation is required in the 5.6 GHz to 6.2 GHz band. The low insertion loss and tight phase balance make it suitable for precision RF front-ends. Consider the 6-SMD footprint for PCB layout constraints. Verify that the operating temperature range of -40°C to +85°C meets your environmental design criteria.

Part Context

This part belongs to the NCS2 series of RF transformers from Mini-Circuits, utilizing Low-Temperature Co-fired Ceramic (LTCC) technology. The series is engineered for miniaturization and high performance in microwave applications. The NCS2-622+ specifically addresses the need for balanced-to-unbalanced conversion in narrowband high-frequency scenarios, offering a compact alternative to traditional wire-wound baluns.

Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Evaluate other Mini-Circuits NCS2 models for similar frequency ranges if impedance ratios differ.
