SB85000

Overview

The SB85000 is a general-purpose RF bias tee module manufactured by Fairview Microwave. It operates within a frequency range of 30 kHz to 85 GHz and utilizes SMA connectors for interfacing. The component is designed to combine DC power with RF signals or separate them, supporting high-frequency applications up to the millimeter-wave spectrum.

Feature Summary

• Integrates DC bias injection with RF signal transmission in a single compact module
• Supports ultra-wideband operation extending into the millimeter-wave frequency range
• Utilizes standard SMA connector interfaces for straightforward system integration

Applications

• RF test and measurement instrumentation requiring combined DC and RF paths
• Millimeter-wave circuit characterization and probing setups
• Active device biasing in high-frequency signal generation systems

Procurement Notes

Verify the specific SMA connector gender and polarity configuration required for your interface before ordering. Confirm that the DC voltage and current ratings provided in the official datasheet align with your bias supply capabilities. Ensure the operating temperature range meets your environmental conditions. Cross-reference the part number with the manufacturer's latest documentation to confirm availability and any potential design revisions.

Selection Notes

Select this component when an ultra-wideband bias tee is required for frequencies up to 85 GHz. The SMA interface offers compatibility with standard laboratory equipment. Consider the physical size and weight constraints if integrating into dense test fixtures. Verify that the insertion loss and VSWR specifications meet the sensitivity requirements of your specific RF application chain.
