• Engineered for low signal attenuation with maximum insertion loss of 1.5dB
• Designed for surface mount integration in compact RF modules

Balun Applications

• RF front-end impedance matching in wireless communication systems
• Balanced-to-unbalanced signal conversion in broadcast receivers
• Integration into compact RF modules requiring 75 Ohm interface compatibility
• Signal processing stages in broadband transmission equipment

Balun Procurement Notes

Verify the specific ordering suffix and package variant against the official Abracon datasheet to ensure compatibility with your PCB footprint and reflow profile requirements. Confirm that the 75/75 Ohm impedance specification aligns with your system's transmission line design. Check for any recent manufacturing updates or lifecycle status changes directly from the manufacturer before finalizing procurement plans.

Balun Selection Notes

Select this component when a wideband solution covering 50MHz to 1.2GHz is required for 75 Ohm systems. Consider the 1.5dB insertion loss limit relative to your link budget constraints. Ensure the module form factor fits within the available board space compared to discrete transformer solutions. Validate that the CMOS-compatible environment does not require additional shielding beyond the module's inherent design.

Balun Part Context

This balun belongs to Abracon's passive RF component portfolio, specifically targeting applications needing reliable impedance transformation without active power sources. It serves as a critical interface element between differential balanced lines and single-ended unbalanced traces in high-frequency circuits. The module approach simplifies assembly compared to discrete winding components, offering consistent performance across production batches.

Balun Replacement Considerations

The ABT-8-75-1-T offers similar 75/75 Ohm impedance matching but covers a narrower frequency range of 45MHz to 870MHz with lower insertion loss. The ABT-8-75-3-T targets higher frequencies from 1GHz to 1.5GHz. Verify frequency coverage and insertion loss requirements carefully when substituting, as these parameters differ significantly between variants.
