4400BL15A0050001E

Balun Overview

The Johanson Technology 4400BL15A0050001E is a wideband ceramic balun designed for RF signal conditioning. It operates within a frequency range of 2.8 GHz to 6 GHz, centered at 4.4 GHz. The component provides a 1:1 impedance ratio with 50 Ohm unbalanced and balanced ports. Key electrical specifications include a maximum insertion loss of 1.5 dB, a minimum return loss of 9.5 dB, and a phase difference of 180° ±12°. It is housed in an SMD/SMT 0805 (2012 metric) package with six PC pads, suitable for board mounting across an operating temperature range of -40°C to +85°C.

Balun Feature Summary

• Provides balanced-to-unbalanced signal conversion with a 1:1 impedance ratio
• Operates as a wideband device covering 2.8 GHz to 6 GHz
• Utilizes compact 0805 surface-mount packaging for space-constrained designs

Balun Applications

• Wireless LAN modules requiring 2.4 GHz and 5 GHz band support
• Wi-Fi 6 and Wi-Fi 6E transceiver interfaces
• Bluetooth low energy antenna matching networks

Balun Procurement Notes

Verify the specific suffix '0001E' against the manufacturer's global part numbering change documentation to ensure compatibility with legacy design files referencing '4400BL15A0050'. Confirm RoHS3 compliance status and moisture sensitivity level (MSL 1) requirements during storage and handling. Cross-reference datasheet revision dates to validate performance parameters against current production batches.

Balun Selection Notes

Select this component when a wideband solution is required for dual-band 2.4 GHz and 5 GHz applications without needing separate filters. The 0805 footprint offers a balance between performance and board space efficiency. Ensure the design accommodates the specified 1.5 dB insertion loss and 9.5 dB return loss limits for optimal signal integrity in high-frequency paths.

Balun Part Context

This balun belongs to Johanson Technology's BL series, which focuses on miniaturized RF components for mobile and IoT devices. The 4400 series specifically targets wideband coverage, replacing discrete transformer and filter combinations. It serves as a critical interface between differential RFIC outputs and single-ended antennas in modern wireless communication standards.

Balun Replacement Considerations

The legacy part number 4400BL15A0050 is identified as a previous version. Verify if the '0001E' suffix denotes a manufacturing or packaging update rather than a functional change. No direct cross-model substitutes are documented in the provided data.
