LDB21942M05C-001

Balun Overview

The LDB21942M05C-001 is a chip multilayer hybrid balun manufactured by Murata Electronics, designed for signal conditioning applications. It operates within a frequency range of 925 MHz to 960 MHz, centered at 942 MHz. The component provides impedance transformation between unbalanced and balanced ports, both rated at 50 Ohms. It utilizes surface mount technology (SMD/SMT) in an 0805 package size, measuring 2.0 mm x 1.25 mm. The device supports a minimum operating temperature of -40°C and a maximum of +85°C. Key electrical specifications include a maximum insertion loss of 1.5 dB.

Balun Feature Summary

• Hybrid balun architecture for RF signal conversion
• Surface mount construction for automated assembly
• Integrated impedance matching for 50 Ohm systems

Balun Applications

• RF front-end modules
• Wireless communication transceivers
• Balanced-to-unbalanced signal conversion circuits

Balun Procurement Notes

Verify the part status as obsolete before procurement planning. Confirm that the specific frequency range of 925 MHz to 960 MHz aligns with the target application requirements. Ensure compatibility with the 0805 footprint and thermal limits during design integration. Check for available replacement components if current stock is unavailable.

Balun Selection Notes

Select this component when a compact hybrid balun is required for frequencies around 942 MHz. The 50/50 Ohm impedance configuration suits standard RF interfaces. Consider the 0805 package dimensions for space-constrained PCB layouts. Evaluate the 1.5 dB insertion loss against system power budget constraints.
