4400BL15A0100001E

Balun Overview

The 4400BL15A0100001E is an RF balun manufactured by Johanson Technology Inc., designed for signal conditioning applications. It operates within a frequency range of 2.8 GHz to 6 GHz, with a center frequency of 4.4 GHz. The component features a 1:2 impedance transformation ratio and maintains a standard 50 Ohm system impedance. Packaged in a compact 0805 (2012 metric) surface-mount device (SMD/SMT) form factor, it supports board mounting. The device exhibits a maximum insertion loss of 1.5 dB and functions reliably across an operating temperature range from -40°C to +85°C.

Balun Feature Summary

• Provides balanced-to-unbalanced signal conversion with a 1:2 impedance transformation ratio
• Operates effectively across a wide RF frequency spectrum from 2.8 GHz to 6 GHz
• Utilizes a compact 0805 surface-mount package for efficient PCB integration

Balun Applications

• RF front-end modules requiring impedance matching
• Wireless communication systems operating in the 2.8-6 GHz range
• Signal conditioning circuits for high-frequency data transmission

Balun Procurement Notes

Verify the specific suffix '001E' against legacy part numbers like 4400BL15A0100E, as manufacturers may update identifiers without changing function. Confirm RoHS3 compliance and MSL level 1 status during sourcing. Ensure the supplier provides official datasheets to validate the 1.5 dB insertion loss and 50 Ohm impedance specifications before finalizing procurement orders.

Balun Selection Notes

Select this component when a 1:2 impedance transformation is required for balanced lines within the 2.8-6 GHz band. The 0805 package suits space-constrained designs. Consider the 1.5 dB insertion loss limit for power-sensitive applications. Verify thermal stability requirements against the -40°C to +85°C operational range. This balun is suitable for replacing older versions if pinout and electrical characteristics remain identical.

Balun Part Context

This balun belongs to Johanson Technology's BL series, specialized for RF signal conditioning. It integrates passive components into a single surface-mount unit, replacing discrete solutions. The 0805 footprint allows for automated assembly. As a filter sub-category product, it aids in maintaining signal integrity by converting unbalanced signals to balanced formats efficiently across specified microwave frequencies.

Balun Replacement Considerations

The part number 4400BL15A0100E is identified as a previous version or alias for this component. Verify electrical equivalence before substitution. No other direct substitute part numbers are publicly confirmed in the provided documentation.
