ADL6331ACCZA-R7

RF Amplifiers Overview

The ADL6331ACCZA-R7 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 requires a single 3.3 V supply. The device draws 80 mA or 160 mA depending on configuration. Key electrical parameters include a noise figure of 7.5 dB, input return loss of 12 dB, and P1dB compression points ranging from 10 dBm to 11.5 dBm. The OIP3 varies between 12.2 dBm and 37.8 dBm, with gain values including 12.7 dB, 14.4 dB, 15.5 dB, 15.7 dB, and 15.9 dB. It is housed in an LGA-24 package.

RF Amplifiers Feature Summary

• Provides broadband variable gain amplification for interfacing RF DACs to power amplifiers
• Operates on a single 3.3 V power supply for simplified system design
• Features low noise figure and high linearity for signal integrity

RF Amplifiers Applications

• Interfacing RF digital-to-analog converters (RF DACs) to single-ended power amplifiers
• Transmit paths in software-defined radio systems
• Broadband communication infrastructure requiring variable gain control

RF Amplifiers Procurement Notes

Verify the specific suffix -R7 indicates reel packaging when ordering. Confirm the LGA-24 package dimensions against your PCB footprint requirements. Ensure the 3.3 V supply capability matches your system voltage rails. Check for RoHS compliance documentation if required by your manufacturing standards. Validate that the operating temperature range of -40 C to +105 C suits your environmental conditions.

RF Amplifiers Selection Notes

Select this component when a wide bandwidth from 380 MHz to 8 GHz is required in the transmit chain. Consider the specific gain steps and linearity metrics like OIP3 for your dynamic range needs. The single-supply operation simplifies power management compared to dual-supply alternatives. Evaluate the LGA-24 package size against available board space constraints.

RF Amplifiers Part Context

This part belongs to the ADL6331 series of transmit variable gain amplifiers. It is distinct from receive VGAs like the ADL6332, which supports higher frequencies up to 15 GHz. The ADL6331-EVALZA evaluation board is available for testing and characterization of this specific device's performance in typical application circuits.

RF Amplifiers Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source material. For potential replacements, consult Analog Devices official cross-reference tools or datasheets for devices with similar frequency ranges and gain specifications.
