2450BL15K0100001E

Overview

The 2450BL15K0100001E is an RF balun manufactured by Johanson Technology Inc., designed for the 2.4GHz to 2.5GHz frequency range. It provides impedance transformation between unbalanced and balanced lines with values of 50 ohms and 100 ohms respectively. The component features a phase difference of 180° ±10°, maximum insertion loss of 1.0dB, and minimum return loss of 9.5dB. It is housed in a compact 0805 (2012 Metric) surface-mount package.

Feature Summary

• Provides conversion between 50-ohm unbalanced and 100-ohm balanced RF signals
• Operates within the 2.4GHz to 2.5GHz ISM band
• Maintains 180-degree phase difference with specified tolerance
• Utilizes integrated passive technology for compact footprint

Applications

• Bluetooth Low Energy (BLE) transceiver interfaces
• Wi-Fi module antenna connections
• Zigbee wireless sensor networks
• ISM band radio frequency circuits

Procurement Notes

Verify the specific suffix K against the official Johanson Technology datasheet to confirm exact electrical tolerances and material specifications. Ensure the ordering part number matches the required impedance configuration and package type. Cross-reference the manufacturer's latest documentation to validate compliance with current RoHS standards and environmental regulations before finalizing procurement orders.

Selection Notes

Select this component when a 50-ohm to 100-ohm impedance transformation is required for 2.4GHz applications. Consider the 0805 package size for space-constrained designs. Evaluate insertion loss and return loss requirements against system sensitivity needs. Compare performance metrics with alternative baluns from the same series if different impedance ratios are necessary.

Part Context
