QPC1008SR

Attenuators Overview

The QPC1008SR is a negative voltage-controlled, wideband GaAs MMIC digital step attenuator combined with a 1 dB voltage variable attenuator (VVA). It features a 5-bit digital control interface and operates from DC to 20 GHz. The device provides precise attenuation steps for RF signal management in high-frequency applications.

Attenuators Feature Summary

• Integrates 5-bit digital step attenuation with an analog voltage variable attenuator
• Wideband operation extending from DC to 20 GHz
• Negative voltage control mechanism for attenuation adjustment

Attenuators Applications

• RF signal path attenuation
• Variable gain control systems
• Test and measurement equipment

Attenuators Procurement Notes

Verify the specific suffix SR against official Qorvo documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with negative voltage control requirements in your circuit design before procurement.

Attenuators Selection Notes

Select this component when wideband attenuation up to 20 GHz is required alongside fine analog resolution. The combination of digital steps and a VVA allows for flexible gain control strategies in complex RF front-ends.

Attenuators Part Context

This part belongs to Qorvo's QPC series of RF attenuators. It utilizes GaAs MMIC technology to achieve performance in the S-band and beyond, offering a compact solution for integrating both digital and analog attenuation capabilities in a single package.

Attenuators Replacement Considerations

Consult official Qorvo substitution guides for verified alternatives. Generic replacements may not match the specific 20 GHz bandwidth or the combined digital/analog control architecture.
