BLN0605LL19R1880A

Balun Overview

The BLN0605LL19R1880A is a surface-mount RF balun manufactured by Pulse Electronics, designed for signal conditioning applications. It operates within the frequency range of 1.805 GHz to 1.99 GHz. The component features an asymmetric impedance configuration with a differential port of 100 Ohms and a single-ended port of 50 Ohms. It is housed in a compact 0202 (0505 metric) package footprint, suitable for space-constrained mobile device designs.

Balun Feature Summary

• Provides balanced-to-unbalanced signal conversion for RF circuits
• Supports asymmetric impedance matching between 50-ohm and 100-ohm ports
• Optimized for operation in the 1.8 to 2.0 GHz frequency band

Balun Applications

• Mobile phone antenna systems
• Wireless LAN modules
• Bluetooth transceivers

Balun Procurement Notes

Verify RoHS compliance status prior to procurement, as public distributor records indicate conflicting information regarding regulatory adherence for this specific part number. Confirm that the received components match the exact BLN0605LL19R1880A designation to ensure correct impedance and frequency specifications. Request manufacturer datasheets to validate performance characteristics against design requirements before finalizing orders.

Balun Selection Notes

Select this component when designing circuits requiring a 100-ohm differential to 50-ohm single-ended transformation in the GSM/DCS bands. The small 0202 footprint makes it appropriate for high-density PCB layouts. Ensure the application environment does not require RoHS compliance if current data suggests non-compliance, or verify updated manufacturing batches for regulatory alignment.

Balun Part Context

This balun belongs to Pulse Electronics' portfolio of passive RF components used for signal integrity management. It serves as a critical interface element between balanced transmission lines and unbalanced circuit nodes. The Type 19 designation refers to the specific internal architecture optimized for the targeted frequency range, distinguishing it from other baluns in the series with different impedance ratios or bandwidths.

Balun Replacement Considerations

Public documentation does not list confirmed direct substitute part numbers for the BLN0605LL19R1880A. Engineers must evaluate alternative baluns based on matching impedance ratios, operating frequency ranges, and physical footprint dimensions to ensure functional compatibility.
