1850BL15B0050001E

Overview

The Johanson Technology Inc. 1850BL15B0050001E is an RF balun designed for signal conditioning applications within the 1.7 GHz to 2 GHz frequency range. It operates as a 1:4 impedance transformer, converting between 50 Ohm and 50 Ohm ports. The component utilizes Surface Mount Device (SMD/SMT) termination and is housed in a compact 0805 (2012 metric) package. It supports reliable operation across a temperature range of -40°C to +85°C.

Feature Summary

• Provides balanced-to-unbalanced signal conversion with a 1:4 transformation ratio
• Engineered for high-frequency RF signal conditioning in mobile communication systems
• Constructed in a small surface-mount footprint for efficient PCB integration

Applications

• GSM/DCS/PCS/CDMA mobile phone transceivers
• RF front-end modules requiring impedance matching
• Wireless communication devices operating in the 1.7-2 GHz band

Procurement Notes

Verify the specific suffix '0050001E' against the manufacturer's official datasheet to confirm the exact impedance configuration and packaging type. Ensure compatibility with the target PCB land pattern for the 0805 package. Cross-reference the RoHS compliance status with current regulatory requirements for the intended market.

Selection Notes

Select this component when a 1:4 balun is required for frequencies between 1.7 GHz and 2 GHz. The 0805 package size suits designs with limited board space. Consider the 50/50 Ohm port configuration for standard RF interface matching. Verify thermal performance meets the -40°C to +85°C operational requirement for the specific application environment.
