BD4859N50100AHF

Balun Overview

The BD4859N50100AHF is an ultralow profile RF balun manufactured by TTM Technologies under the Xinger brand. It operates within a frequency range of 4.8 GHz to 5.9 GHz, providing signal conditioning between unbalanced and balanced circuits. The component features a 50 Ohm unbalanced port and a 100 Ohm balanced port. It utilizes a surface-mount (SMD/SMT) installation type in a 0404 (1010 metric) package. Key electrical specifications include a maximum insertion loss of 0.6 dB and a minimum return loss of 13 dB. The device supports a board mount configuration with a standard operating temperature range from -55°C to +85°C.

Balun Feature Summary

• Converts single-ended signals to differential signals for high-frequency applications
• Provides impedance transformation between 50 Ohm and 100 Ohm systems
• Designed for compact PCB layouts using an ultralow profile form factor

Balun Applications

• Wireless local area network (WLAN) transceivers
• Bluetooth low energy (BLE) modules
• Zigbee and other IEEE 802.15.4 based devices
• Ultra-wideband (UWB) communication systems

Balun Procurement Notes

Verify the specific suffix 'N50100AHF' to confirm the 50/100 Ohm impedance configuration and RoHS compliance status. Ensure the procurement channel provides official datasheets matching the Xinger series documentation. Confirm that the received components match the 0404 package dimensions and pinout requirements for the target design.

Balun Selection Notes

Select this component when a wide bandwidth covering both 5 GHz WLAN and Bluetooth bands is required in a minimal footprint. The 100 Ohm balanced output is suitable for transformer-coupled or differential input stages. Consider the 0.6 dB insertion loss for sensitive receiver chains. Evaluate thermal management capabilities within the specified -55°C to +85°C operational range.

Balun Part Context

This part belongs to the Xinger BD series of ultralow profile baluns, designed for modern wireless standards requiring high integration. It replaces larger through-hole or older SMD balun technologies. The product line focuses on miniaturization while maintaining stable phase and amplitude balance across the designated frequency spectrum.

Balun Replacement Considerations

Check for cross-reference parts within the same Xinger family offering different impedance ratios or frequency ranges. Verify mechanical compatibility with existing footprints if substituting with similar 0404 packages.
