RFSA3613TR7

Attenuators Overview

The RFSA3613TR7 is a silicon-based digital step attenuator manufactured by Qorvo. It operates within a frequency range of 5 MHz to 6 GHz and features a 50 Ohm impedance. The device provides a total attenuation range of 31.5 dB with a resolution of 0.5 dB steps, controlled via a 6-bit interface. It utilizes a QFN-16 package for surface mount installation.

Attenuators Feature Summary

• Provides precise digital control over signal attenuation levels across a wide bandwidth
• Integrates a 6-bit control interface for granular adjustment in 0.5 dB increments
• Designed for high linearity and low insertion loss in compact silicon technology

Attenuators Applications

• RF front-end modules requiring variable gain control
• Test and measurement equipment calibration systems
• Wireless communication base station architectures

Attenuators Procurement Notes

Verify the specific suffix 'TR7' against official Qorvo documentation to confirm reel packaging specifications. Ensure compatibility with standard SMD reflow processes. Cross-reference the datasheet for any recent product change notices that may affect pinout or electrical characteristics before finalizing procurement plans.

Attenuators Selection Notes

Select this component when a 6-bit resolution is required for fine-tuned attenuation adjustments up to 6 GHz. Consider the QFN-16 footprint for space-constrained designs. Evaluate thermal performance requirements as the device relies on silicon technology, ensuring adequate heat dissipation paths are integrated into the PCB layout for sustained operation.

Attenuators Part Context

This part belongs to the RFSA series of digital step attenuators from Qorvo. It complements other models like the RFSA3513 and RFSA2033 by offering higher resolution (0.5 dB vs 1 dB) within the same 6 GHz frequency band. The series targets applications demanding precise amplitude control without the complexity of analog voltage-controlled alternatives.

Attenuators Replacement Considerations

The RFSA3613SR is a similar variant within the same family. Verify if the 'SR' suffix indicates a different tape-and-reel specification or testing criteria compared to the 'TR7' designation. Both share identical core electrical parameters but require confirmation of mechanical and packaging interchangeability.
