CX2109NL

Balun Overview

The CX2109NL is an RF balun transformer manufactured by Pulse Electronics. It operates within a frequency range of 4.5MHz to 3GHz and provides a 50/50 Ohm impedance transformation between balanced and unbalanced lines. The component utilizes a 5-SMD module package for surface mount installation. Key electrical specifications include a maximum insertion loss of 3.5dB and a phase difference of 20 degrees. It is compliant with RoHS3 standards and carries an EAR99 classification.

Balun Feature Summary

• Provides balanced-to-unbalanced signal conversion across a wide RF spectrum
• Designed for surface mount integration in compact electronic assemblies
• Ensures signal integrity through specified phase and impedance characteristics

Balun Applications

• RF circuit balancing and impedance matching
• Wireless communication systems operating in the specified frequency band
• Signal processing modules requiring differential to single-ended conversion

Balun Procurement Notes

Verify the specific datasheet version and RoHS3 compliance status prior to procurement. Confirm that the 5-SMD module footprint matches the target PCB layout dimensions. Ensure the operating environment remains within the defined thermal limits to maintain performance stability. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability and authenticity.

Balun Selection Notes

Select this component when a wideband RF balun is required for frequencies extending up to 3GHz. The 50/50 Ohm configuration suits standard RF transmission line applications. Consider the 5-SMD package size for space-constrained designs. Verify that the 3.5dB insertion loss and 20-degree phase difference meet the system's signal integrity requirements.

Balun Part Context

This component belongs to Pulse Electronics' portfolio of audio and signal transformers, specifically categorized under RF baluns. It serves as a passive device for managing signal balance in high-frequency circuits. The product line focuses on providing reliable impedance transformation for modern wireless and communication technologies.

Balun Replacement Considerations

Consult official Pulse Electronics documentation for verified substitute part numbers. Do not assume functional equivalence with generic RF baluns without verifying impedance, frequency range, and package compatibility against the original specification sheet.
