The AD-FMCOMMS5-EBZ is a high-speed analog module designed to showcase the AD9361 in multiple-input, multiple-output (MIMO) applications. The AD9361 is a high performance, highly integrated RF transceiver that operates from 70 MHz to 6 GHz, and supports bandwidths from less than 200 kHz to 56 MHz. The AD-FMCOMMS5-EBZ supports dual AD9361 devices, allowing for the creation of a 4x4 MIMO system. This platform is intended to enable the prototyping and development of many software defined radio applications, such as active antennas, transmit beamforming, and receive angle of arrival systems. The AD-FMCOMMS5-EBZ board has both wideband channels covering the full 6 GHz range, as well as narrowband channels matched to 2.4GHz. The AD-FMCOMMS5-EBZ also contains dual ADG918 SPDT switches, which create a calibration matrix between the two AD9361s. This switch matrix hardware, combined with the Analog Devices supplied API software, allow for a full digital and RF synchronization between the two AD9361s. The providing APIs also support full independent device configuration of the two AD9361s.
Because the AD-FMCOMMS5-EBZ supports both narrow and wideband input and output connectivity, it provides RF engineers the ability to connect the AD9361 to a RF test bench (vector signal analyzer, signal generator, etc.) and measure narrowband performance, as well as providing software and system engineers the ability to quickly prototype across the full 6 GHz operating range. Additionally the AD-FMCOMMS5-EBZ allows for both AD9361 devices to receive an on-board generated external LO signal, which can provide improved RF performance.
