2450BM18A001E

Overview

The Johanson Technology Inc. 2450BM18A001E is a surface-mount balun designed for the 2.4 GHz to 2.5 GHz frequency range. It utilizes a 1206 (3216 metric) package and provides impedance transformation between 50 ohms and 100 ohms. The component features a maximum insertion loss of 4.2 dB, with an alternative specification noting up to 5.0 dB. It operates within a temperature range of -40°C to +85°C and supports SMD/SMT termination types.

Feature Summary

• Provides balanced-to-unbalanced signal conversion for RF applications
• Integrates impedance matching between 50-ohm and 100-ohm systems
• Optimized for compact 1206 surface-mount footprint

Applications

• Wireless LAN (WLAN) transceivers
• Bluetooth module interfaces
• Zigbee communication devices

Procurement Notes

Verify the specific insertion loss requirement against your design specifications, as documentation indicates values of both 4.2 dB and 5.0 dB. Confirm that the 1206 package dimensions align with your PCB layout constraints. Ensure the operating temperature range meets your environmental standards. Cross-reference the manufacturer part number to avoid confusion with similar series components.

Selection Notes

Select this component when a 1206 form factor is required for space-constrained designs. It is suitable for applications needing direct interface between 50-ohm single-ended lines and 100-ohm differential pairs. Consider the specified insertion loss limits when calculating total link budget. Verify compatibility with standard reflow soldering profiles for SMD components.

Part Context

This part belongs to the BM series of signal conditioning components from Johanson Technology. It functions as a passive RF balun, distinct from active amplifiers or filters. The designation indicates its placement in the 2.4 GHz ISM band spectrum, commonly used for short-range wireless data transmission protocols.
