WTBL2012Z0U007PB

Overview

The WTBL2012Z0U007PB is an RF balun manufactured by Walsin Technology Corporation, designed for surface mount applications in the 0805 (2012 Metric) package. It operates within a frequency range of 50MHz to 1.2GHz, providing impedance transformation between 75 Ohm and 75 Ohm ports. The component supports signal balancing functions required in radio frequency circuits.

Feature Summary

• Provides balanced-to-unbalanced signal conversion with 75 Ohm to 75 Ohm impedance matching
• Operates across a wide frequency spectrum from 50MHz to 1.2GHz
• Designed for multi-transmitter operation on a single RF antenna system

Applications

• RF signal balancing in communication systems
• Multi-transmitter antenna sharing configurations
• High-frequency circuit impedance matching

Procurement Notes

Verify the specific datasheet version and impedance characteristics against the target design requirements. Confirm that the 0805 footprint matches the PCB layout constraints. Ensure the operating frequency range covers the intended application bandwidth without significant insertion loss deviations.

Selection Notes

Select this component when a compact 75 Ohm to 75 Ohm balun solution is needed for frequencies up to 1.2GHz. The 0805 package offers space efficiency for dense layouts. Consider the specific insertion loss and return loss parameters defined in the official datasheet for critical RF performance needs.
