AD-FMCOMMS2-EBZ User Guide

The AD-FMComms2-EBZ is an FMC board for the AD9361, a highly integrated RF Agile Transceiver™. While the complete chip level design package can be found on the the ADI web site. Information on the card, and how to use it, the design package that surrounds it, and the software which can make it work, can be found here.

The purpose of the AD-FMComms2-EBZ is to provide an RF platform to which shows maximum performance of the AD9361. It’s expected that the RF performance of this platform can meet the datasheet specifications without issues at 2.4 GHz, and not much anywhere else. This is due to the external Johanson Technology's 2450BL15B050E 2.45 GHz Balun that is on the board. This balun is rated for a operating frequency of 2400~2500 MHz.

This platform is primarily for hardware / RF investigation and bring up of various waveforms from a RF team before their custom hardware is complete, where they want to see waveforms at their frequency of interest, and are not afraid of changing out the balun if necessary. (Have a look in the Configuration sections).

The AD-FMComms2-EBZ board is very similar to the AD-FMComms3-EBZ board with only one exception, the RX/TX RF differential to single ended balun/transformer. The AD-FMComms3-EBZ is more targetted for wider tuning range applications, that is why we use the TCM1-63AX+ from mini Circuits as the RF transformer of choice. We affectionately call the FMCOMMS3-EBZ the “Software Engineers” platform, and the FMCOMMS2-EBZ, the “RF Engineers” platform to denote the difference.

Warning

All the boards described on this page include ESD (electrostatic discharge) sensitive devices. Electrostatic charges as high as 4000V readily accumulate on the human body and 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.
