RFSA3413TR7

Attenuators Overview

The RFSA3413TR7 is a silicon-based digital step attenuator manufactured by Qorvo, designed for surface-mount applications in the QFN-16 package. It operates within a frequency range of 5 MHz to 6 GHz with a nominal 50 Ohm impedance. The device provides a total attenuation range of 15 dB using 4-bit control, achieving a precise step size of 1 dB per channel. Key electrical specifications include an insertion loss of 1.4 dB and a power rating of 27 dBm. It functions on a supply voltage between 2.7 V and 5.5 V and supports an operating temperature range from -40°C to +105°C.

Attenuators Feature Summary

• Provides precise digital attenuation control via a 4-bit interface with 1 dB resolution steps.
• Engineered for wideband operation across the 5 MHz to 6 GHz spectrum.
• Features low insertion loss characteristics suitable for signal integrity maintenance.
• Supports high-temperature operation up to +105°C for robust environmental performance.

Attenuators Applications

• RF signal path management in wireless communication infrastructure
• Test and measurement equipment requiring variable attenuation
• Mobile device front-end modules for gain control
• Base station transceiver systems

Attenuators Procurement Notes

Verify component authenticity through authorized Qorvo distributors or certified partners. Confirm RoHS compliance status and specific packaging options such as cut tape or reel availability prior to ordering. Ensure that the procurement source provides valid traceability documentation. Check for any recent product change notifications regarding manufacturing updates. Validate that the supplied units match the exact RFSA3413TR7 designation to avoid integration errors.

Attenuators Selection Notes

Select this component when a compact, digitally controlled attenuator is required for frequencies up to 6 GHz. The 4-bit architecture offers sufficient granularity for many standard RF applications while minimizing control line complexity. Consider the 1.4 dB insertion loss impact on system noise figure. Evaluate the 27 dBm power handling against maximum expected signal levels. The wide operating temperature range makes it suitable for industrial and outdoor environments.

Attenuators Part Context

This part belongs to the RFSA341 series of digital step attenuators from Qorvo. It utilizes silicon technology to deliver cost-effective RF control solutions. The series is designed to replace traditional analog attenuators in modern electronic designs. It integrates seamlessly into PCB layouts due to its small QFN-16 footprint. The family targets applications demanding reliable gain adjustment without significant signal degradation.

Attenuators Replacement Considerations

Direct substitutes within the same series include the RFSA3513TR7, which offers a wider 31 dB range with 5-bit control. For lower attenuation requirements, the RFSA2033TR7 provides a 25 dB range but operates at a fixed 5 V supply. Designers should verify pin compatibility and control logic differences when cross-referencing these alternatives.
