SB3000

Overview

The SB3000 is an SMA bias tee module manufactured by Fairview Microwave, designed for general-purpose RF applications. It operates within a frequency range of 10 MHz to 3 GHz and utilizes SMA connectors on all ports. The component supports a maximum DC current rating of 3000 mA and a voltage rating of 50 VDC. This configuration allows for the simultaneous transmission of RF signals and DC power through a single coaxial line, facilitating the powering of active components such as amplifiers or antennas without signal interruption.

Feature Summary

• Integrates RF signal path with DC bias injection capability
• Utilizes standard SMA connector interfaces for compatibility
• Supports high current DC bias up to 3000 mA
• Operates across a wide frequency spectrum from 10 MHz to 3 GHz

Applications

• Powering active RF components like low-noise amplifiers
• Biasing antenna systems in communication setups
• Test and measurement equipment requiring combined signal and power delivery
• General-purpose RF circuit integration

Procurement Notes

Verify the specific datasheet version for the SB3000 to confirm electrical tolerances and connector gender specifications prior to integration. Ensure that the system's DC power supply does not exceed the rated 50 VDC limit to prevent component damage. Confirm mechanical fitment of SMA connectors within the assembly constraints. Cross-reference the manufacturer's documentation for any updates regarding material composition or environmental ratings.

Selection Notes

Select the SB3000 when a compact solution is required to combine RF and DC paths using SMA interfaces. Consider this model for applications demanding high DC current capacity up to 3000 mA within the 3 GHz bandwidth. Evaluate the need for general-purpose biasing versus specialized high-frequency variants. Ensure the operating environment aligns with the component's specified frequency and power limits.
