NCS4-63+

Balun Overview

The NCS4-63+ is an LTCC surface-mount RF balun transformer manufactured by Mini-Circuits. It operates within a frequency range of 4.5 GHz to 6 GHz, providing a 1:4 impedance transformation ratio with a nominal 50-ohm single-ended to 200-ohm balanced configuration. The component utilizes Thin Film LTCC technology for high reliability and features a compact 6-SMD, no-lead package suitable for automated assembly. It exhibits low insertion loss and supports operation across standard industrial temperature ranges.

Balun Feature Summary

• Integrates 1:4 impedance transformation for balanced-to-unbalanced signal conversion
• Utilizes robust Thin Film LTCC construction for thermal stability
• Designed for compact surface-mount integration in dense PCB layouts

Balun Applications

• Wireless local area network (WLAN) transceivers
• Bluetooth module interfaces
• Zigbee communication devices
• RF front-end signal conditioning circuits

Balun Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with the manufacturer or authorized distributor before procurement. Ensure that the ordering suffix matches the required packaging format, such as cut tape or reel, to align with production line requirements. Confirm that the component meets all applicable environmental regulations for the target market.

Balun Selection Notes

Select this component when a 1:4 balun function is required specifically within the 4.5 GHz to 6 GHz operational band. The choice is driven by the need for LTCC technology to ensure performance consistency under varying thermal conditions. Consider the 6-SMD footprint constraints and the necessity for low-loss signal integrity in high-frequency wireless applications.

Balun Part Context

This device belongs to the NCS series of RF transformers from Mini-Circuits, which are engineered for signal conditioning in modern wireless systems. The series leverages LTCC manufacturing to provide reliable impedance matching between single-ended and balanced ports. It serves as a critical interface component in RF chains where phase balance and amplitude symmetry are essential for system performance.

Balun Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative baluns only after verifying that the replacement meets the identical 4.5–6 GHz frequency range, 1:4 ratio, and 6-SMD package dimensions.
