AT10030A-30-U

Attenuators Overview

The AT10030A-30-U is a USB programmable digital step attenuator manufactured by Amtery Corporation. It operates within a frequency range of 10 MHz to 30 GHz and features a 50Ω impedance. The device provides a maximum attenuation of 31.5 dB with a resolution of 0.5 dB. A key technical specification is its integrated insertion loss compensation function, which ensures the actual attenuation value matches the set value without additional loss.

Attenuators Feature Summary

• USB-controlled digital operation for precise attenuation adjustment
• Integrated insertion loss compensation to maintain accurate attenuation values
• Wideband coverage from 10 MHz to 30 GHz
• High-resolution attenuation steps of 0.5 dB

Attenuators Applications

• RF test and measurement systems requiring variable attenuation
• Wireless communication equipment calibration
• Signal integrity testing in high-frequency environments

Attenuators Procurement Notes

Verify the specific suffix 'U' corresponds to the USB interface variant when ordering. Confirm that the required frequency range up to 30 GHz aligns with your system specifications. Ensure compatibility with the provided control software before integration. Check for any updated datasheets regarding S-parameter performance at higher frequencies.

Attenuators Selection Notes

Select this model if USB connectivity is preferred over other digital interfaces. Consider the 0.5 dB resolution requirement against standard 1 dB or 0.25 dB alternatives. Evaluate the 31.5 dB maximum attenuation against system dynamic range needs. Verify that the 50Ω impedance matches the surrounding RF circuitry to prevent signal reflections.

Attenuators Part Context

This component belongs to Amtery's USB Programmable Attenuator series. It complements their broader portfolio of RF components, including synthesizers and directional couplers. The product line focuses on providing precise, digitally controlled RF signal management solutions for laboratory and industrial applications.

Attenuators Replacement Considerations

The AT10030A-30-P is a related digital step attenuator from the same manufacturer. Verify interface differences, as the 'P' suffix may indicate a different control method than the USB interface of the 'U' variant. Compare frequency ranges and attenuation steps to ensure functional equivalence.
