ADRF5717BCCZN-R7

Attenuators Overview

The ADRF5717BCCZN-R7 is a silicon digital step attenuator manufactured by Analog Devices Inc. It provides a total attenuation range of 48 dB with discrete steps of 16 dB, controlled via a 2-bit interface. The device operates across a frequency range from 9 kHz to 30 GHz and maintains a 50-ohm impedance. Key electrical specifications include an insertion loss of 2.9 dB. It is housed in an LGA-20 package and supports glitch-free operation for reliable signal control.

Attenuators Feature Summary

• Supports glitch-free operation for stable signal attenuation
• Provides 48 dB total attenuation range in 16 dB increments
• Operates effectively up to 30 GHz frequency

Attenuators Applications

• RF test and measurement equipment
• Wireless communication systems
• Phased array antenna beamforming networks

Attenuators Procurement Notes

Verify the specific suffix R7 indicates reel packaging when sourcing. Confirm the LGA-20 package dimensions against your PCB footprint requirements. Ensure compatibility with 3.3 V logic levels for control signals. Check current supply status as availability may be limited or subject to factory special orders.

Attenuators Selection Notes

Select this component for applications requiring wideband attenuation up to 30 GHz. The 2-bit resolution offers coarse adjustment suitable for gain staging rather than fine-tuning. Consider the 2.9 dB insertion loss impact on system noise figure. Evaluate thermal management needs given the LGA-20 package constraints.

Attenuators Part Context

This part belongs to the ADRF5717 series of silicon digital attenuators. It shares functional similarities with other members like the ADRF5716 but differs in bit resolution and step size. The series is designed for high-frequency RF applications requiring precise digital control over signal amplitude.
