BLGE4-252R+

Balun Overview

The Mini-Circuits BLGE4-252R+ is a miniature ceramic RF balun transformer designed for surface mount applications. It operates within the 2400 to 2500 MHz frequency range and provides an impedance ratio of 1:4 (secondary to primary). The component features a 50-ohm system impedance, making it suitable for high-frequency signal balancing tasks in compact electronic designs.

Balun Feature Summary

• Miniature ceramic construction for surface mount integration
• Balanced-to-unbalanced signal conversion capability
• Optimized for 2400 to 2500 MHz operational frequencies

Balun Applications

• Wireless communication systems operating in the 2.4 GHz band
• RF front-end modules requiring impedance transformation
• Compact consumer electronics with space constraints

Balun Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly from Mini-Circuits official documentation before procurement. Ensure that the GE0805C-9 case style footprint matches the target PCB layout requirements. Confirm that the 1:4 impedance ratio aligns with the circuit design specifications to prevent signal integrity issues.

Balun Selection Notes

Select this component when a balanced output is required from an unbalanced source within the 2.4 to 2.5 GHz spectrum. The 1:4 impedance transformation ratio is critical for matching 50-ohm systems to higher impedance loads. Consider the surface mount package size for assembly compatibility and thermal management needs in dense PCB layouts.

Balun Part Context

This component belongs to Mini-Circuits' line of LTCC (Low Temperature Co-fired Ceramic) RF transformers. These devices are engineered for high reliability and consistent performance in microwave and radio frequency applications. The BLGE series specifically targets applications demanding precise impedance balancing and minimal signal loss in compact form factors.

Balun Replacement Considerations

Consult Mini-Circuits official substitution guides for verified equivalent part numbers. Direct replacements must maintain the 1:4 impedance ratio and 2400-2500 MHz frequency coverage. Verify mechanical footprint compatibility to ensure seamless integration without PCB redesign.
