SB65000A

Overview

The SB65000A is a 1.85 mm bias tee RF adapter manufactured by Fairview Microwave, designed for high-frequency signal distribution and DC injection. It operates within a frequency range of 30 kHz to 70 GHz with a characteristic impedance of 50 Ohms. The component features three female jack ports with normal polarity, constructed from stainless steel. It supports a maximum DC current rating of 500 mA and a voltage rating of 25 Volts. The unit exhibits a Voltage Standing Wave Ratio (VSWR) of 2.5 and weighs approximately 27.216 grams.

Feature Summary

• Integrates DC bias injection into RF signal paths via a T-connector topology
• Supports ultra-wideband operation extending up to 70 GHz
• Rated for continuous DC currents up to 500 mA at 25 Volts

Applications

• High-frequency test and measurement setups requiring simultaneous RF and DC signals
• Characterization of active components such as amplifiers and mixers
• Millimeter-wave system integration and calibration

Procurement Notes

Verify the specific manufacturing date code and lot number upon receipt to ensure compliance with project requirements. Confirm that the physical condition of the stainless steel body and connector interfaces matches the specifications provided in the official datasheet. Ensure handling procedures protect the precision 1.85 mm connectors from contamination or mechanical damage during installation.

Selection Notes

Select this component when a 1.85 mm interface is required for frequencies up to 70 GHz. It is appropriate for applications needing integrated DC biasing capabilities without external combiners. Consider the VSWR specification of 2.5 when evaluating signal integrity requirements. Ensure the system can accommodate the specified 500 mA DC current limit and 25 Volt maximum rating.
