ADL6337ACCZB

Overview

The ADL6337ACCZB is a single-channel, high-linearity transmit variable gain amplifier (VGA) manufactured by Analog Devices Inc. It operates within the 1350 MHz to 2800 MHz frequency range and is designed to interface RF digital-to-analog converters, transceivers, and systems on a chip with power amplifiers. The device features an integrated RF balun and supports differential inputs with a single-ended output. Key electrical specifications include a power gain of 35.5 dB, an output third-order intercept point (OIP3) of 42.5 dBm, and a noise figure of 4.5 dB at zero decibel digital step attenuator setting. It utilizes a 32-lead, 5 mm × 5 mm LFCSP package.

Feature Summary

• Integrates a glitch-free digital step attenuator with 31.5 dB attenuation range and 0.5 dB resolution for precise signal control.
• Features fully programmable operation via a 3-wire or 4-wire serial peripheral interface for configuration flexibility.
• Incorporates an integrated RF balun to enable differential input and single-ended output configurations.
• Constructed using advanced silicon germanium bipolar complementary metal-oxide semiconductor process technology.

Applications

• 2G/3G/4G/LTE in-band full-duplex and time-division duplex broadband communication systems
• General wireless communication infrastructure equipment
• RF DAC and transceiver interfaces requiring high linearity

Procurement Notes

Verify the specific suffix ACCZB against the manufacturer's ordering guide to confirm the exact frequency variant and packaging type. Ensure compatibility with the required SPI interface voltage levels and supply current requirements during system integration. Confirm availability status as distribution channels may vary.

Selection Notes

Select this component when interfacing between baseband processing units and power amplifiers in the 1350 MHz to 2800 MHz band. Consider the 35.5 dB gain and 42.5 dBm OIP3 for linear transmission requirements. Evaluate the 5 V single-supply operation and 460 mA current consumption against thermal management capabilities.

Part Context

The ADL6337 belongs to a family of transmit VGAs covering frequencies from 500 MHz to 5200 MHz. Variants A, B, C, and D cover distinct sub-bands. The ACCZB designation corresponds to the B-variant optimized for the 1350 MHz to 2800 MHz range. This series addresses the need for compact, high-performance solutions in modern wireless transceiver architectures.

Replacement Considerations

Other variants within the ADL6337 family (ADL6337-A, ADL6337-C, ADL6337-D) share the same pinout and functionality but operate in different frequency ranges. Verify that the target application frequency aligns with the 1350 MHz to 2800 MHz specification before substituting.
