ADL6331ACCZA

RF Amplifiers Overview

The ADL6331ACCZA is a transmit variable gain amplifier (TxVGA) from Analog Devices, designed for RF signal chains. It operates within a frequency range of 380 MHz to 8 GHz and utilizes a 3.3 V supply. The device features dual channels with configurable gains including 12.7 dB, 14.4 dB, 15.5 dB, 15.7 dB, and 15.9 dB. Key performance metrics include a noise figure of 7.5 dB, P1dB compression points of 10 dBm and 11.5 dBm, and OIP3 values of 12.2 dBm and 37.8 dBm. It draws 80 mA or 160 mA depending on configuration. Packaged in a 24-LGA (4x4) case, it supports temperatures from -40°C to +105°C.

RF Amplifiers Feature Summary

• Integrates balanced-to-unbalanced conversion and bypass attenuators for direct RF DAC to single-ended PA interfacing
• Provides dual independent variable gain amplifier channels with programmable attenuation control
• Supports wideband operation across the 380 MHz to 8 GHz spectrum for versatile RF applications

RF Amplifiers Applications

• Interface between RF digital-to-analog converters and power amplifiers
• Wireless infrastructure base station transmitters
• Test and measurement equipment requiring precise gain control

RF Amplifiers Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific suffix R7 indicates reel packaging if required by assembly processes. Check current availability status as supply may be limited or subject to factory special orders. Ensure compatibility with LGA-24 soldering profiles during procurement planning.

RF Amplifiers Selection Notes

Select this component when interfacing RF DACs directly to single-ended power amplifiers without external baluns. Consider the dual-channel architecture for applications requiring independent gain control per path. Evaluate the 3.3 V supply requirement against system power constraints. Verify that the 24-LGA package size fits the PCB layout constraints and thermal management requirements.

RF Amplifiers Part Context
