SB5792

Overview

The SB5792 is an SMA Bias Tee RF adapter manufactured by Fairview Microwave. It operates within a frequency range of 100 kHz to 12.4 GHz and maintains a 50 Ohm impedance. The component features three SMA female jacks with normal polarity, facilitating signal distribution while allowing DC bias injection. It is rated for a maximum DC current of 700 mA and a voltage of 50 Volts. The unit exhibits a Voltage Standing Wave Ratio (VSWR) of 1.6. Constructed from stainless steel, the adapter weighs 19 grams and is packaged individually in a bag.

Feature Summary

• Integrates DC bias injection capability into an RF signal path via a tee configuration
• Supports high-frequency operation up to 12.4 GHz with low signal reflection
• Provides robust electrical isolation for DC inputs up to 50 Volts and 700 mA

Applications

• Biasing active RF components such as amplifiers or oscillators
• Injecting control voltages into microwave test and measurement setups
• Integrating DC power lines into RF transmission paths without signal degradation

Procurement Notes

Verify that the required DC bias parameters do not exceed the 50 Volt and 700 mA ratings specified for this model. Confirm compatibility with SMA female connectors on both the input and output ports. Ensure the operating environment supports the stainless steel construction and that the 100 kHz lower frequency limit meets system requirements.

Selection Notes

Select this component when a passive method is needed to combine RF signals with DC power in a 50 Ohm system. It is suitable for applications requiring operation up to 12.4 GHz where minimal VSWR is critical. Consider the physical dimensions and weight if space constraints exist in dense RF assemblies.
