SB4030

Overview

The SB4030 is a 2.92mm bias tee adapter manufactured by Fairview Microwave, designed for RF applications spanning 500 MHz to 40 GHz. It features a 50 Ohm impedance and is constructed from stainless steel. The component supports a maximum DC bias current of 1000 mA and a voltage rating of 50 Volts DC. It utilizes female jack connectors with normal polarity on both RF sides, ensuring compatibility within standard 2.92mm systems.

Feature Summary

• Provides simultaneous RF signal transmission and DC bias injection or blocking
• Operates across a wide frequency range up to 40 GHz
• Supports high DC current loads up to 1000 mA

Applications

• Amplifier Biasing
• DC Return / Block
• Transmitting Power

Procurement Notes

Verify the specific connector gender and polarity requirements against system schematics before integration. Confirm that the operating environment remains within the specified 50 VDC and 1000 mA limits to ensure component integrity. Check official documentation for precise mechanical dimensions and mounting constraints relevant to the target assembly.

Selection Notes

Select this component when a broadband bias solution is required for frequencies starting at 500 MHz. Ensure the host system utilizes 2.92mm interfaces to maintain proper impedance matching. Consider the stainless steel construction for durability in demanding environments where higher thermal or mechanical stability is necessary compared to other materials.

Part Context

This adapter belongs to the RF Adapters - Tee category, specifically functioning as a bias tee. It integrates RF and DC paths into a single compact module. The design facilitates efficient power delivery to active components without disrupting the high-frequency signal path, serving as a critical interface element in complex RF test and measurement setups.
