2450FB15A0100001E

Overview

The Johanson Technology Inc. 2450FB15A0100001E is an RF balun filter combo designed for the 2.4GHz to 2.5GHz frequency range. It provides a 1:2 impedance transformation ratio, converting between 50 Ohm unbalanced and 100 Ohm balanced ports. Housed in a compact 0805 (2012 Metric) surface-mount package with six PCB pads, this component integrates filtering capabilities alongside balancing functions. Key electrical specifications include a maximum insertion loss of 1.5dB, a minimum return loss of 9.5dB, and a phase difference of 180° ±10°. The device complies with RoHS3 standards and is classified under ECCN EAR99.

Feature Summary

• Integrates balun and low-pass filter functions within a single surface-mount component
• Provides 1:2 impedance transformation between 50 Ohm unbalanced and 100 Ohm balanced ports
• Optimized for operation within the 2.4GHz to 2.5GHz ISM band

Applications

• Wireless LAN (WLAN) transceiver front-ends
• Bluetooth module signal conditioning
• Zigbee communication interface circuits

Procurement Notes

Verify the specific suffix '0100001E' against official Johanson Technology documentation to ensure correct impedance and pad configuration. Confirm that the 6-pad footprint matches the target PCB layout, as variations exist within the series. Check current RoHS3 compliance status directly from the manufacturer's latest datasheet before finalizing procurement specifications.

Selection Notes

Select this component when a combined balancing and filtering solution is required to reduce board space. Ensure the design accommodates the 100 Ohm balanced port requirement, distinguishing it from 50/50 Ohm variants. Validate that the 1.5dB insertion loss meets system link budget requirements for the intended wireless application.

Part Context

This part belongs to the Johanson 2450 series, which focuses on integrated passive devices for 2.4GHz applications. Unlike discrete baluns, this model combines filtering to suppress harmonics. It differs from similar parts like the 2450FB15K0005001E by offering a 1:2 ratio instead of 1:1, and utilizes a 6-pad footprint compared to the 8-pad alternative.
