ADL6317ACCZ

Overview

The ADL6317ACCZ is a transmit variable gain amplifier (VGA) manufactured by Analog Devices Inc. using an advanced silicon germanium (SiGe), bipolar complementary metal oxide semiconductor (BiCMOS) process. It provides an interface from radio frequency digital-to-analog converters (RF DACs), transceivers, and systems on a chip (SoC) to power amplifiers. The device operates within an RF output frequency range of 1500 MHz to 3000 MHz. It features integrated balun and hybrid couplers for high-performance RF capability. To optimize performance versus power level, the ADL6317 includes a voltage variable attenuator (VVA), high linearity amplifiers, and a digital step attenuator (DSA). All integrated devices are programmable via a 4-wire serial port interface (SPI).

Feature Summary

• Integrated balun with bias-tee to supply RF DAC outputs.
• Voltage variable attenuator (VVA) attenuation range with on-chip DAC: 20.5 dB.
• Two-stage high linearity amplifiers.
• RF digital step attenuator (DSA) attenuation range: 15.5 dB with 0.5 dB step resolution.

Applications

• 2G/3G/4G/long-term evolution (LTE) in FDD/TDD broadband communication systems

Procurement Notes

Verify that the ordering suffix ACCZ corresponds to the specific package variant and temperature rating documented in the official Analog Devices ordering guide. Confirm RoHS compliance status and lead time requirements directly with authorized distributors or the manufacturer before placing orders. Ensure the procurement documentation matches the exact part number to avoid receiving incorrect package types or revisions.

Selection Notes

Select the ADL6317 when interfacing RF DACs or transceivers to power amplifiers in the 1500 MHz to 3000 MHz range. Consider this component for designs requiring integrated baluns, VVA control via SPI or analog voltage, and DSA functionality. Evaluate thermal resistance and PCB layout requirements due to the LGA package and exposed pads. Verify compatibility with single 5 V supply operation and 1.8 V to 3.3 V logic levels.

Part Context

The ADL6317 belongs to a family of transmit VGAs designed for broadband communication systems. Related devices include the ADL6316, which covers the 500 MHz to 1000 MHz frequency range. The ADL6317 specifically targets higher frequency applications up to 3000 MHz. It is manufactured using SiGe BiCMOS technology, distinguishing it from purely CMOS solutions. The device integrates multiple signal chain components into a single compact package.
