• Supports 50-ohm balanced and unbalanced interfaces
• Optimized for WiMAX frequency bands
• Utilizes silver-plated platinum termination technology

Applications

• WiMAX wireless communication systems
• RF front-end signal conditioning modules
• Balanced-to-unbalanced signal conversion circuits
• Compact RF transceiver designs

Procurement Notes

Verify the specific legacy part number designation when sourcing, as the manufacturer may utilize alternative naming conventions for identical components. Confirm that the required 6-pad footprint aligns with the target PCB layout specifications. Ensure compliance with RoHS directives if environmental standards are mandatory for the assembly process. Cross-reference datasheet revisions to confirm electrical parameter consistency prior to final procurement decisions.

Selection Notes

Select this component for applications requiring simultaneous impedance transformation and frequency filtering in limited space. The 0805 package size suits high-density board layouts. Verify that the operating frequency range fully encompasses the target signal bandwidth. Consider the thermal and mechanical properties of the ceramic construction for robustness in mobile devices.

Part Context

This component belongs to the Johanson Technology FB series, which specializes in signal conditioning solutions. The series focuses on combining multiple RF functions into miniature packages. These devices are engineered to reduce component count and simplify circuit design for wireless infrastructure and portable electronic devices requiring efficient signal management.

Replacement Considerations

The legacy part number 2500FB16A0400E represents the same functional specification. When substituting, ensure the replacement matches the 0805 6-pad footprint exactly. Verify that the new batch maintains the same Ag/Pt termination characteristics and frequency response curves to prevent circuit performance deviation.
