ADRF5720BCCZN-R7

Attenuators Overview

The ADRF5720BCCZN-R7 is a silicon digital attenuator manufactured by Analog Devices Inc., designed for high-frequency applications. It features a 6-bit resolution with a least significant bit (LSB) step size of 0.5 dB, providing a total attenuation range up to 31.5 dB. The device operates across a wide frequency spectrum from 9 kHz to 40 GHz, making it suitable for broadband RF systems. It utilizes a single-channel configuration and is housed in an LGA-24 package. The component supports surface mount installation and functions within a temperature range of -40°C to +105°C, powered by a 3.3 V supply voltage.

Attenuators Feature Summary

• Provides precise digital control over signal attenuation levels through a 6-bit interface.
• Supports ultra-wideband operation extending from low frequencies up to 40 GHz.
• Integrates a compact LGA-24 package optimized for high-density circuit board layouts.

Attenuators Applications

• Phased array antenna beamforming networks
• Test and measurement instrumentation equipment
• Wireless communication base station front-ends

Attenuators Procurement Notes

Verify the specific suffix R7 against official Analog Devices documentation to confirm reel packaging specifications. Ensure compatibility with LGA-24 footprint requirements during PCB design. Confirm current availability status as distribution channels may indicate limited stock or restricted supply conditions. Validate RoHS compliance details directly from the manufacturer's datasheet before procurement.

Attenuators Selection Notes

Select this component when designing systems requiring attenuation at frequencies exceeding standard microwave limits. The 0.5 dB LSB resolution offers fine-grained control necessary for accurate gain adjustment in sensitive RF paths. Consider the 40 GHz upper limit when evaluating performance against lower-frequency alternatives. Ensure thermal management strategies account for the specified operating temperature range.
