ADL6317ACCZ-R7

Overview

The ADL6317ACCZ-R7 is a transmit variable gain amplifier (VGA) manufactured by Analog Devices Inc. It interfaces RF DACs, transceivers, and SoCs to power amplifiers within an operating frequency range of 1500 MHz to 3000 MHz. The device integrates a voltage variable attenuator (VVA), high linearity amplifiers, and a digital step attenuator (DSA). It operates on a single 5 V supply and features a 38-terminal LGA package measuring 10.5 mm × 5.5 mm.

Feature Summary

• Integrates a 20.5 dB voltage variable attenuator with internal DAC or external analog control
• Includes a 15.5 dB digital step attenuator with 0.5 dB resolution
• Features integrated balun and quadrature hybrid couplers for wideband matching
• Fully programmable via a 4-wire serial port interface

Applications

• FDD/TDD broadband communication systems
• 2G/3G/4G/LTE transmitter designs
• RF DAC and transceiver to power amplifier interfaces

Procurement Notes

Verify the specific suffix ACCZ against official documentation to confirm lead-free status and RoHS compliance. Confirm the package type matches the required 38-terminal LGA form factor. Ensure the ordering code aligns with the intended frequency range specifications.

Selection Notes

Select this component for applications requiring precise gain control in multi-carrier transmitters. Evaluate the integration of VVA and DSA stages against system dynamic range requirements. Consider the SiGe BiCMOS process technology for high linearity performance at target frequencies.

Part Context

This part belongs to the ADL631x family of transmit VGAs designed for wireless infrastructure. While other variants cover different frequency bands, this model specifically targets the 1500 MHz to 3000 MHz spectrum. It serves as a critical link between baseband processing and RF power stages.

Replacement Considerations

Consult official substitution guides for compatible devices within the ADL631x family. Verify pin compatibility and electrical specifications before replacing existing components in established designs.
