FMBL1005

Balun Overview

The FMBL1005 is a surface-mount balun manufactured by Fairview Microwave, designed for RF signal conversion between balanced and unbalanced lines. It operates within a frequency range of 500 MHz to 2 GHz at an impedance of 50 Ohms. The component provides a phase shift of 180 degrees with an amplitude balance of ±0.4 dB and a phase balance of ±7 degrees. It is rated for 100 Watts of power handling and utilizes a 3-SMD module package.

Balun Feature Summary

• Provides balanced-to-unbalanced signal conversion with a 180-degree phase shift
• Maintains tight amplitude balance of ±0.4 dB across the operating band
• Ensures precise phase balance of ±7 degrees for signal integrity
• Supports high power handling up to 100 Watts in a compact SMT form factor

Balun Applications

• RF front-end circuits requiring impedance transformation
• Balanced mixer architectures
• Differential signal processing systems
• Wireless communication transceivers

Balun Procurement Notes

Verify the specific datasheet version to confirm pinout orientation and soldering profile requirements for the 3-SMD module. Ensure that the selected component matches the 50 Ohm to 25 Ohm impedance specification required by the target circuit design. Cross-reference the manufacturer's part number FMBL1005 with distributor listings to confirm current availability status and lead times before finalizing procurement plans.

Balun Selection Notes

Select this component when a compact surface-mount solution is needed for converting between 50 Ohm unbalanced and 25 Ohm balanced lines. The wide frequency coverage from 500 MHz to 2 GHz makes it suitable for various broadband applications. Consider the 100 Watt power rating for high-power signal paths and ensure the PCB layout accommodates the specific thermal and electrical requirements of the 3-SMD package.
