CX2038LNLT

Balun Overview

The CX2038LNLT is an RF balun transformer manufactured by Pulse Electronics, designed for surface-mount applications. It operates within a frequency range of 4.5 MHz to 1.5 GHz and provides a balanced-to-unbalanced impedance transformation of 75 ohms to 75 ohms. The component features a maximum insertion loss of 2.0 dB and a minimum return loss of 14 dB. It is housed in a compact 5-SMD module package with dimensions of 3.81 mm in length and width, and 2.79 mm in height. The device supports a current rating of 30 mA and functions reliably across an operating temperature range from -40°C to +85°C.

Balun Feature Summary

• Provides balanced-to-unbalanced signal conversion for RF circuits
• Supports wideband operation from 4.5 MHz to 1.5 GHz
• Designed for surface-mount technology integration
• Maintains low insertion loss and high return loss performance

Balun Applications

• RF signal processing circuits requiring impedance matching
• Balanced line interfacing in communication systems
• Signal conditioning modules operating in the VHF/UHF bands

Balun Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for recent Product Change Notices (PCN) regarding manufacturing updates. Ensure the specific suffix matches the required packaging format, as availability may vary between tape-and-reel and other configurations. Validate datasheet revisions against current production standards before finalizing procurement specifications.

Balun Selection Notes

Select this component when a 75-ohm balanced-to-unbalanced transformation is required within the 4.5 MHz to 1.5 GHz spectrum. Consider the 5-SMD footprint for space-constrained PCB layouts. Evaluate thermal performance against the -40°C to +85°C operating range. Compare insertion loss specifications against system budget requirements to ensure signal integrity is maintained across the intended frequency band.

Balun Part Context

This part belongs to the CX series of audio and signal transformers produced by Pulse Electronics. The series includes various configurations for different impedance ratios and frequency ranges. The CX2038LNLT specifically addresses RF balun needs, distinguishing itself from standard audio transformers by its high-frequency capabilities and balanced output characteristics suitable for RF transmission lines.

Balun Replacement Considerations

Public records indicate that the CX2038LNL is a related variant, though it utilizes tray packaging instead of tape-and-reel. Verify if the functional electrical parameters remain identical for direct substitution. Check for any end-of-life notices or product change notifications that might affect long-term supply stability for this specific reel-packaged version.
