ZFBT-282-1.5A+

Overview

The ZFBT-282-1.5A+ is a wideband bias tee from Mini-Circuits designed for RF signal conditioning. It operates within a frequency range of 10 MHz to 2800 MHz, providing a DC path with a maximum current rating of 1.5 A and a voltage limit of 30 V. The component features an insertion loss of 1.6 dB maximum and supports up to 30 dBm power handling. Constructed with SMA connectors, it ensures reliable signal integrity across the specified bandwidth while maintaining low noise characteristics suitable for precision applications.

Feature Summary

• Integrates DC bias injection into RF transmission lines without disrupting signal integrity
• Supports high current delivery up to 1.5 A for active component powering
• Maintains consistent impedance matching across a broad microwave frequency spectrum
• Utilizes robust SMA interface for secure mechanical and electrical connections

Applications

• Biasing low-noise amplifiers in receiver front-ends
• Powering active antennas in communication systems
• Signal conditioning in test and measurement instrumentation
• RF circuit prototyping and development environments

Procurement Notes

Verify that the specific order matches the ZFBT-282-1.5A+ designation to ensure correct current and voltage ratings. Confirm connector type compatibility with existing SMA infrastructure. Check for RoHS compliance status if environmental regulations apply. Ensure storage conditions align with manufacturer guidelines to preserve performance specifications over time.

Selection Notes

Select this component when a wideband solution covering 10 MHz to 2.8 GHz is required. Consider the 1.5 A current capacity for powering higher-drain active devices. Evaluate the 30 dBm power handling against system peak levels. Choose based on the need for minimal insertion loss in critical signal paths.

Part Context

This part belongs to the ZFBT series of bias tees from Mini-Circuits, which are engineered for general-purpose RF applications. The series offers various configurations tailored to different frequency ranges and current requirements. The ZFBT-282-1.5A+ specifically addresses needs for moderate current delivery within a wideband operational window, fitting into standard RF subsystem architectures.

Replacement Considerations

Consult official Mini-Circuits documentation for direct substitutes or alternative models within the ZFBT family that match specific frequency or current constraints. Verify pinout and connector compatibility before swapping components to ensure seamless integration.
