3700BL15B0100001E

Balun Overview

The 3700BL15B0100001E is an RF balun manufactured by Johanson Technology Inc., designed for operation within the 3.4GHz to 4GHz frequency range. It provides impedance transformation between unbalanced and balanced circuits with a 50 Ohm to 100 Ohm ratio. The component utilizes a surface-mount 0805 (2012 metric) package, measuring 2.00mm in length, 1.25mm in width, and 0.65mm in maximum height. It supports SMD/SMT termination styles and is classified under signal conditioning components.

Balun Feature Summary

• Provides RF balance-to-unbalance conversion for wireless applications
• Integrates impedance matching between 50 Ohm and 100 Ohm systems
• Supports compact surface-mount assembly via 0805 footprint

Balun Applications

• WiMAX transceiver front-end modules
• RFID reader antenna interfaces
• Wireless LAN uplink/downlink signal paths

Balun Procurement Notes

Verify that the specific part number matches the required 3.4GHz to 4GHz operational bandwidth and 50/100 Ohm impedance configuration. Confirm compatibility with the 0805 surface-mount package dimensions and soldering thermal profiles. Ensure the selected variant aligns with the intended RF circuit design requirements for balance-to-unbalance conversion.

Balun Selection Notes

Select this component when a compact balun is required for frequencies between 3.4GHz and 4GHz. The 0805 package size suits space-constrained designs. Consider the 50 Ohm to 100 Ohm impedance transformation capability for interfacing different circuit stages. Evaluate the surface-mount termination style against available PCB layout constraints and assembly processes.

Balun Part Context

This device belongs to Johanson Technology's integrated passive component portfolio, specifically within the balun category. It serves as a signal conditioning element for RF systems, replacing discrete transformer solutions. The component integrates magnetic and dielectric materials to achieve performance in a small form factor suitable for modern electronic assemblies.

Balun Replacement Considerations

Direct substitutes include other Johanson Technology baluns operating in the 3.4GHz to 4GHz range with similar impedance ratios and package sizes. Verify electrical parameters such as insertion loss and return loss before substitution. Cross-reference pin configurations and thermal characteristics to ensure functional equivalence.
