5400BL15K0050001E

Balun Overview

The 5400BL15K0050001E is an RF balun manufactured by Johanson Technology Inc., designed for signal conditioning in wireless applications. It operates within a frequency range of 4.9 GHz to 5.87 GHz, centered around 5.4 GHz for Wi-Fi usage. The component features a 50/50 Ohm impedance configuration with a maximum insertion loss of 1.2 dB and a minimum return loss of 8.5 dB. It maintains a phase difference of 180° ±10°. Packaged in a compact 0805 (2012 metric) surface-mount footprint, it supports operation between -40°C and +85°C.

Balun Feature Summary

• Provides balanced-to-unbalanced signal conversion for RF circuits
• Optimized for high-frequency Wi-Fi band operations
• Compact surface-mount design for space-constrained PCB layouts

Balun Applications

• Wi-Fi module antenna interfaces
• Wireless LAN transceiver circuits
• RF signal path balancing networks

Balun Procurement Notes

Verify the specific suffix K against the official Johanson Technology datasheet to confirm electrical tolerances and pinout compatibility. Ensure the 0805 package dimensions align with the target PCB footprint. Confirm RoHS3 compliance status if required by regional regulations. Cross-reference the manufacturer part number with distributor listings to avoid obsolete or alternate revision variants.

Balun Selection Notes

Select this component when a compact balun is required for 5 GHz Wi-Fi bands. The 0805 package suits dense layouts. Verify that the 1.2 dB insertion loss meets system link budget requirements. Ensure the 50/50 Ohm impedance matches both the transceiver output and antenna input ports. Check thermal ratings for high-temperature environments.

Balun Part Context

This part belongs to Johanson Technology's BL series of integrated passive components. These baluns replace discrete LC networks, reducing board space and improving performance consistency. The 5400 series is specifically engineered for modern wireless standards requiring precise phase and amplitude balance at microwave frequencies.
