FMBT1623

Overview

The FMBT1623 is a general-purpose RF bias tee module manufactured by Fairview Microwave. It operates within a frequency range of 10 MHz to 2.5 GHz and utilizes SMA connectors for signal interfacing. The device provides DC bias injection capabilities while maintaining RF isolation. Key electrical specifications include a typical maximum Voltage Standing Wave Ratio (VSWR) of 1.5:1 and an RF-to-bias isolation level of approximately 40 dB. This component is designed to facilitate the integration of DC power sources into RF signal paths without significant signal degradation.

Feature Summary

• Provides broadband DC bias injection across a wide frequency spectrum
• Maintains high isolation between RF signal and DC bias ports
• Features low VSWR for efficient signal transmission
• Utilizes standard SMA connector interfaces for easy integration

Applications

• RF circuit testing and measurement setups requiring simultaneous DC bias and RF signals
• Integration with active RF components such as amplifiers or mixers needing external DC power
• General-purpose RF system design where DC bias must be added to existing RF lines

Procurement Notes

Verify that the required frequency range aligns with the specified 10 MHz to 2.5 GHz operational limits. Ensure compatibility with SMA connector types used in your existing RF infrastructure. Confirm that the typical 40 dB isolation and 1.5:1 VSWR meet your system's performance requirements. Check manufacturer documentation for specific DC bias voltage and current ratings to avoid component damage. Validate that the module packaging meets your handling and storage standards.

Selection Notes

Select this component when a general-purpose solution is needed for adding DC bias to RF signals within the specified bandwidth. Consider the SMA interface if it matches your system's connector requirements. Evaluate the typical isolation and VSWR values against your sensitivity needs. Compare against other bias tees if higher frequency ranges or different connector types are necessary. Ensure the physical form factor fits your available space constraints.
