LDB21869M15C-001

Balun Overview

The LDB21869M15C-001 is a multi-layer hybrid balun from the LDB21 series, designed for RF and wireless applications. It operates within a frequency range of 824MHz to 915MHz. The component provides an impedance transformation between 50 ohms (unbalanced) and 150 ohms (balanced). It features a maximum insertion loss of 1.3dB and utilizes an 0805 (2012 metric) surface-mount package. The device supports board mounting and functions within a temperature range of -40°C to +85°C.

Balun Feature Summary

• Multi-layer hybrid construction for compact integration
• Balanced-to-unbalanced signal conversion capability
• Surface-mount design for automated assembly

Balun Applications

• RF front-end modules in wireless communication devices
• Antenna interface circuits operating in sub-GHz bands
• Signal conditioning for balanced transmission lines

Balun Procurement Notes

Verify component status carefully as this part is officially listed as obsolete with end-of-life notifications documented by the manufacturer. Confirm availability through authorized distributors or secondary markets if production continuity is required. Ensure that any replacement strategy accounts for the discontinued status to avoid supply chain disruptions in new designs.

Balun Selection Notes

Select this component when a 50/150 ohm impedance transformation is specifically required within the 824MHz to 915MHz frequency band. The 0805 package size suits space-constrained layouts. Consider the 1.3dB insertion loss specification for power budget calculations. Verify thermal compatibility with the -40°C to +85°C operating range for the intended environment.
