ZFBT-6G+

Overview

The ZFBT-6G+ is a coaxial bias tee from Mini-Circuits designed for applications over a wide frequency range of 10 to 6000 MHz. It provides 40 mA of DC current capability while maintaining low insertion loss across the specified bandwidth. The component features SMA connectors and operates at an impedance of 50 Ohms. Packaged in case style K18, it supports RoHS compliance standards.

Feature Summary

• Provides simultaneous RF signal transmission and DC bias injection via a single port
• Designed for low insertion loss performance across a broad microwave frequency spectrum
• Supports up to 40 mA DC current capacity for powering active components

Applications

• Biasing low-noise amplifiers (LNAs) in RF front-end modules
• Powering active antennas requiring combined signal and power delivery
• Test and measurement setups involving RF circuit characterization

Procurement Notes

Verify that the specific order suffix matches the required configuration, as standard variants may differ from specialized versions like the FT variant. Confirm connector type compatibility with existing SMA infrastructure. Ensure the 40 mA current rating aligns with the target device's DC requirements. Check RoHS compliance documentation if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a compact solution is needed to combine DC power and RF signals without separate cabling. The 50 Ohm impedance ensures compatibility with standard RF systems operating between 10 MHz and 6 GHz. Consider the physical dimensions of case style K18 for integration into tight spaces. Evaluate the maximum current limit against the load requirements to prevent saturation or damage.

Part Context

This part belongs to Mini-Circuits' family of general-purpose bias tees, which facilitate the integration of DC power into RF signal paths. Similar models include the TCBT-6G+, offering alternative form factors for different mounting needs. These components are essential for simplifying circuit designs by reducing the number of interconnects required for active RF devices.

Replacement Considerations

The TCBT-6G+ serves as a public confirmed substitute part number within the same manufacturer's lineup, offering similar electrical specifications with potential mechanical differences.
