AT10012A-30-P

Attenuators Overview

The AT10012A-30-P is a digital step attenuator manufactured by Amtery Corporation, designed for RF applications spanning from 15 MHz to 12 GHz. It provides a total attenuation range of 31.5 dB with a precise step size of 0.5 dB. The device operates within a standard 50 Ohm impedance environment and features SMA connectors for module integration. This component serves as a programmable solution for signal level control in high-frequency systems.

Attenuators Feature Summary

• Digital control architecture enabling precise step-wise attenuation adjustments
• Broad operational frequency range supporting microwave applications up to 12 GHz
• SMA connector interface facilitating direct module integration

Attenuators Applications

• RF test and measurement equipment requiring variable signal levels
• Wireless communication base stations for power management
• Satellite ground station signal conditioning modules

Attenuators Procurement Notes

Verify the specific datasheet version (e.g., CP10012A-10.pdf referenced in some listings) against the exact part number AT10012A-30-P to ensure parameter alignment. Confirm SMA connector polarity and pinout compatibility with your system design before procurement. Check RoHS compliance status directly with the manufacturer or authorized distributor documentation.

Attenuators Selection Notes

Select this component when a wide bandwidth covering both VHF/UHF and microwave bands is required. The 0.5 dB step resolution offers finer control compared to standard 1 dB or 3 dB steps. Ensure the host system supports the digital control interface protocol specified in the official Amtery technical documentation.

Attenuators Part Context

This model belongs to Amtery's digital step attenuator series, which includes USB-programmable variants like the AT10012A-30-U. The 'P' suffix typically denotes the standard digital control interface variant, distinct from USB-controlled versions. It complements other passive components like directional couplers in complete RF front-end designs.

Attenuators Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Cross-reference with other Amtery digital attenuators only if interface protocols and frequency ranges match exactly. Verify mechanical footprint and connector types before considering any alternative models.
