LDB213G7020C-001

Balun Overview

The LDB213G7020C-001 is a multi-layer hybrid balun manufactured by Murata Electronics, designed for RF applications. It operates within a frequency range of 3.4 GHz to 4 GHz. The device features an impedance configuration of 50 Ohms on the single-ended side and 200 Ohms on the differential side. It is housed in a compact 0805 (2012 metric) surface-mount package. The component specifies a maximum insertion loss of 2.3 dB. It supports a minimum operating temperature of -40°C and complies with RoHS3 standards.

Balun Feature Summary

• Multi-layer hybrid construction for balanced-to-unbalanced signal conversion
• Optimized for high-frequency RF operation between 3.4 GHz and 4 GHz
• Compact 0805 surface-mount footprint for space-constrained designs

Balun Applications

• RF front-end modules in wireless communication devices
• Balanced antenna interface circuits
• Differential signal processing in RF transceivers

Balun Procurement Notes

Verify the specific ordering suffix to ensure the correct impedance and frequency specifications match the design requirements. Confirm that the 0805 package dimensions align with the PCB land pattern. Check for RoHS3 compliance status if environmental regulations are mandatory for the target market. Ensure storage conditions account for moisture sensitivity levels prior to reflow soldering.

Balun Selection Notes

Select this component when a balanced output from a 50 Ohm source is required in the 3.4–4 GHz band. The 200 Ohm differential impedance suits specific balanced load topologies. Consider the 2.3 dB insertion loss budget against system gain requirements. The hybrid technology offers stability compared to discrete implementations. Evaluate thermal performance at the -40°C lower limit for harsh environment deployments.

Balun Part Context

This part belongs to the LDB21 series of multi-layer hybrid baluns from Murata Electronics. These components integrate passive elements into a single ceramic structure to provide phase and amplitude balance. The series targets miniaturization needs in modern RF systems where discrete baluns would consume excessive board area.

Balun Replacement Considerations

Direct substitutes must match the 3.4–4 GHz frequency range, 50/200 Ohm impedance ratio, and 0805 package size. Verify equivalent insertion loss and return loss characteristics. Cross-reference manufacturer datasheets for pinout compatibility and thermal handling capabilities.
