CX2049LANL

Balun Overview

The CX2049LANL is an RF balun transformer manufactured by Pulse Electronics, designed for single-ended to balanced signal conversion. It operates within a frequency range of 250kHz to 500MHz and features a 1:8 center-tapped impedance configuration. The component utilizes a 5-SMD surface-mount package and exhibits a maximum insertion loss of 3.0dB with a minimum return loss of 8dB. It is RoHS3 compliant, classified under ECCN EAR99, and has a Moisture Sensitivity Level (MSL) of 1.

Balun Feature Summary

• Provides single-ended to balanced signal transformation using a 1:8 center-tapped architecture
• Operates across a wide frequency spectrum from 250kHz to 500MHz
• Utilizes a compact 5-SMD surface-mount package for automated assembly

Balun Applications

• RFID transponder circuits requiring balanced feed lines
• Single-chip RFID reader antenna interfaces
• Ultra-wideband (UWB) communication systems

Balun Procurement Notes

Verify the specific suffix 'L' against the official datasheet to confirm the 1:8CT impedance ratio and physical dimensions. Ensure the ordering quantity aligns with the manufacturer's standard packaging requirements. Confirm that the application environment remains within the specified operating temperature range of -40°C to +85°C. Check for any regional compliance documentation such as REACH or CA Prop 65 statements if required by your supply chain regulations.

Balun Selection Notes

Select this component when a high-impedance transformation ratio is required for RFID or UWB applications. The 1:8 center-tapped design suits antennas needing specific impedance matching. Compare insertion loss specifications against system budget constraints. Consider the 5-SMD footprint for PCB space limitations. Verify compatibility with the target frequency band before finalizing the design.

Balun Part Context

This part belongs to the Pulse Electronics CX2049 series of RF baluns. It shares the same operational frequency range and package type as variants like CX2049LNLT but differs in impedance transformation ratio. The series is optimized for compact wireless devices where size and performance are critical. Other models in the family may offer different ratios or slightly varied electrical characteristics while maintaining the same form factor.

Balun Replacement Considerations

The CX2049LNLT is a documented alternative within the same series. Verify that the impedance ratio difference does not impact the circuit design. Ensure pinout compatibility and mechanical fit remain unchanged during substitution.
