Analog Devices EVAL-AD-FMCOMMS5-EBZ Evaluation Board is a high-speed analog module designed for the AD9361 Wideband Transceiver IC in multiple-input, multiple-output (MIMO) applications. The high performance, highly integrated AD9361 integrated RF transceiver that operates from 70 MHz to 6 GHz, and supports bandwidths from less than 200kHz to 56MHz. The AD-FMCOMMS5-EBZ supports dual AD9361 devices, enabling the creation of a 4x4 MIMO system. This platform is intended to allow the prototyping and development of many software-defined radio applications, including active antennas, transmit beamforming, and receive angle of arrival systems. The AD-FMCOMMS5-EBZ board includes both wideband channels covering the full 6GHz range, as well as narrowband channels matched to 2.4GHz. 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 6GHz 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.
