BD2425J50100AHF

Balun Overview

The BD2425J50100AHF is an ultralow profile RF balun transformer manufactured by TTM Technologies. It operates within a frequency range of 2.4 to 2.5 GHz, facilitating balanced-to-unbalanced signal conversion. The component features a 50 Ohm unbalanced port and a 100 Ohm balanced port, with an impedance ratio of 1:2. Key electrical specifications include an insertion loss between 0.55 and 0.75 dB, amplitude balance of ±0.3 to 0.5 dB, and phase balance of 2 to 5 degrees. It supports a power handling capacity of 2 W and exhibits return loss ranging from 14 to 22 dB. The device is housed in a compact 0805 (2012 metric) surface-mount package.

Balun Procurement Notes

Verify the specific suffix AHF against the manufacturer's current datasheet to confirm RoHS compliance status and material composition. Ensure that the ordering quantity aligns with the supplier's minimum order requirements and packaging formats. Cross-reference the part number with official distributor catalogs to validate authenticity and avoid counterfeit components during procurement.

Balun Selection Notes

Select this component when a 1:2 impedance transformation is required between 50 Ohm and 100 Ohm lines in the 2.4-2.5 GHz band. Consider its physical dimensions and thermal characteristics relative to the PCB layout constraints. Evaluate the insertion loss and balance parameters against system sensitivity requirements to ensure adequate signal integrity.

Balun Part Context

This balun belongs to the Xinger series of ultralow profile transformers produced by TTM Technologies. These components are designed for high-volume manufacturing and integration into compact wireless devices. The product line emphasizes miniaturization while maintaining stable RF performance across industrial temperature ranges.

Balun Replacement Considerations

Direct substitutes may include other 0805 footprint baluns with matching 2.4-2.5 GHz frequency ranges and 1:2 impedance ratios. Verify that alternative parts meet or exceed the specified insertion loss, amplitude balance, and power handling capabilities before implementation.
