LDB21881M05C-001

Balun Overview

The LDB21881M05C-001 is a chip multilayer hybrid balun designed for signal conditioning applications. It operates within a frequency range of 869 MHz to 894 MHz, centered at 881 MHz with a bandwidth of 25 MHz. The component provides impedance transformation between unbalanced and balanced ports, both rated at 50 Ohms. It features a maximum insertion loss of 1.5 dB and is housed in an 0805 (2012 metric) surface-mount package.

Balun Feature Summary

• Converts single-ended signals to differential signals with precise impedance matching
• Optimized for narrowband RF applications in the GSM/DCS bands
• Compact surface-mount design suitable for space-constrained PCB layouts

Balun Applications

• GSM base station transceivers
• DCS mobile communication modules
• RF front-end signal conditioning circuits

Balun Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure compatibility with required impedance and frequency specifications. Confirm that the 0805 footprint matches the target PCB design constraints. Check for RoHS compliance status if environmental regulations apply to the end product assembly process.

Balun Selection Notes

Select this component when a compact solution is required for converting 50-ohm single-ended lines to 50-ohm differential pairs in the 869–894 MHz range. Ensure the application demands low insertion loss below 1.5 dB. Consider thermal management requirements associated with surface-mount devices in high-density RF environments.
