2450BL15B0200001E

Overview

The Johanson Technology Inc. 2450BL15B0200001E is an RF balun designed for the 2.4GHz to 2.5GHz frequency range. It provides a 50-ohm unbalanced to 200-ohm balanced impedance transformation in a compact 0805 (2012 metric) surface-mount package. Key electrical specifications include a maximum insertion loss of 1.0dB, a minimum return loss of 9.5dB, and a phase difference of 180° ±10°. The component operates within a temperature range of -40°C to +85°C and complies with RoHS3 standards.

Feature Summary

• Provides balanced-to-unbalanced signal conversion for wireless applications
• Integrated passive design reduces component count compared to discrete solutions
• Compact 0805 footprint suitable for space-constrained PCB layouts

Applications

• Wi-Fi modules operating in the 2.4GHz ISM band
• Bluetooth Low Energy (BLE) transceivers
• Zigbee and IEEE 802.15.4 wireless sensor networks

Procurement Notes

Verify the specific impedance configuration required by the circuit design, as this part number denotes a 50/200 ohm transformation ratio. Confirm that the 0805 package dimensions align with the target PCB land pattern. Ensure compliance with RoHS3 regulations if applicable to the final assembly requirements. Cross-reference the manufacturer part number against distributor databases to confirm current availability and lead times before finalizing procurement plans.

Selection Notes

Select this component when a 1:4 impedance transformation ratio is necessary between the RF source and load. The 0805 package size offers a balance between performance and board space efficiency. Consider the 1.0dB insertion loss specification for link budget calculations. Verify that the 2.4GHz to 2.5GHz frequency coverage matches the specific channel requirements of the target wireless protocol.
