ZFBT-4R2G+

Overview

The ZFBT-4R2G+ is a coaxial bias tee manufactured by Mini-Circuits, designed for applications requiring low insertion loss over a wide frequency range from 10 to 4200 MHz. It features an SMA connector termination style and utilizes a SPST contact form. The device has a specified insertion loss of 1.6 dB and is housed in the K18 case style.

Feature Summary

• Provides DC bias injection while maintaining RF signal integrity across a broad bandwidth
• Constructed with SMA connectors for reliable coaxial interfacing
• Engineered for low insertion loss performance in RF circuits

Applications

• RF circuit biasing
• Test and measurement equipment
• Communication systems

Procurement Notes

Verify the specific datasheet version and environmental rating (ENV28) before procurement. Confirm that the SMA interface and K18 package match your system requirements. Ensure the operating frequency range of 10 to 4200 MHz aligns with your application needs. Check for RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when a coaxial bias tee is needed for frequencies up to 4.2 GHz. Consider the 1.6 dB insertion loss specification for signal budget calculations. The K18 case style should be evaluated for physical space constraints. Verify compatibility with existing SMA connectors in the design.

Part Context

This part belongs to the Mini-Circuits bias tee product line, specifically designed for RF applications. It serves as a passive component to combine DC power and RF signals on a single transmission line. The ZFBT series offers various frequency ranges and connector options for different system requirements.

Replacement Considerations

Check Mini-Circuits documentation for direct substitutes within the ZFBT series. Verify frequency coverage and connector type compatibility before substitution. Ensure electrical specifications such as insertion loss meet or exceed original requirements.
