1850BL15B0200001E

Overview

The Johanson Technology Inc. 1850BL15B0200001E is an RF balun designed for signal conditioning applications within the 1.7 GHz to 2.0 GHz frequency range, centered at 1.85 GHz. It features a 1:4 impedance transformation ratio, converting from a 50-ohm unbalanced port to a 200-ohm balanced port. The component utilizes a surface-mount 0805 (2012 metric) package and supports SMD/SMT termination types. It operates reliably within a temperature range of -40°C to +85°C.

Feature Summary

• Provides 1:4 impedance transformation between 50-ohm unbalanced and 200-ohm balanced ports
• Optimized for high-frequency signal conditioning in the 1.7 GHz to 2.0 GHz band
• Compact 0805 surface-mount footprint suitable for space-constrained PCB layouts

Applications

• RF front-end modules requiring balanced-to-unbalanced conversion
• Wireless communication systems operating in the 1.7–2.0 GHz spectrum
• Signal conditioning circuits for high-frequency solutions

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current global part number list, as Johanson Technology has implemented numbering revisions that may affect availability or documentation references. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into production schedules.

Selection Notes

Select this component when a 1:4 impedance step-up is required for balanced loads in the 1.7–2.0 GHz range. Ensure the design accommodates the 0805 package dimensions and thermal characteristics. Validate insertion loss and return loss specifications against system link budget requirements for optimal performance.

Part Context

This device belongs to the BL series of integrated passive components manufactured by Johanson Technology. It serves as a replacement for legacy part numbers such as 1850BL15B200. The component is categorized under RF baluns and is intended for use in modern wireless infrastructure and consumer electronics requiring compact signal processing elements.

Replacement Considerations

The legacy part number 1850BL15B200 is identified as a previous version of this component. Designers should verify pinout compatibility and electrical parameter equivalence before substituting older inventory with the current 1850BL15B0200001E designation.
