EVAL-ADRV904x

Integrated 8T8R RF Transceiver with Digital Pre-Distortion and Crest Factor Reduction.

Overview

The EVAL-ADRV904x, is an FMC radio card designed to showcase the ADRV9040 and ADRV9044, highly integrated, radio frequency (RF) agile transceivers offering 8 independently controlled transmitters, 2 observation receiver inputs for monitoring transmitter channels, 8 independently controlled receivers, integrated local oscillator (LO) and clock synthesizers, digital front-end (DFE) with crest factor reduction (CFR) and digital pre-distortion (DPD), and digital signal processing functions providing a complete transceiver solution.

The device provides the high radio performance and low-power consumption demanded by cellular infrastructure applications and massive MIMO base stations, offering advanced DFE capabilities on an integrated ARM Cortex-A55 quad-core processor.

Recommendations

People who follow the flow that is outlined, have a much better experience with things. However, like many things, documentation is never as complete as it should be. If you have any questions, feel free to ask on our EngineerZone forums, but before that, please make sure you read our documentation thoroughly.

To better understand the ADRV9040 / ADRV9044, we recommend to use the EVAL-ADRV904x evaluation board.

Warning

All the products described on this page include ESD (electrostatic discharge) sensitive devices. Electrostatic charges as high as 4000V readily accumulate on the human body or test equipment and can discharge without detection. Although the boards feature ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. This includes removing static charge on external equipment, cables, or antennas before connecting to the device.
