AD-FMCOMMS2/3/4/5-EBZ Introduction
The AD-FMCOMMS[2345]-EBZ cards are a high-speed analog module designed to showcase the AD9361 or 9364, a high performance, highly integrated RF agile transceiver intended for use in RF applications, such as 3G and 4G base station applications and software defined radios. Its programmability and wideband capability make it ideal for a broad range of transceiver applications. The device combines an RF front end with a flexible mixed-signal baseband section and integrated frequency synthesizers, simplifying design-in by providing a configurable digital interface to a processor or FPGA. The AD9361 and AD9364 chip operates in the 70MHz to 6GHz range, covering most licensed and unlicensed bands. The boards, due to discrete external components may have less performance on some of the RF input/output connectors (for example - the FMCOMMS2 and specific connectors on the FMCOMMS5 are specifically tuned to 2.4GHz). The AD9361 and AD9364 both supports channel bandwidths from less than 200kHz to 56MHz by both changing sample rate, and by changing digital filters, and decimation inside the device itself.
The difference between the AD9361 (2 Rx, 2 Tx) and AD9364 (1 Rx, 1 Tx) is the number of channels. Software, HDL, pinout, etc - is all exactly the same.
The AD-FMCOMMS2-EBZ board, in simple terms, is just the AD9361 in a 2 x 2 RF configuration. Hence the features and capabilities of the device extends to the board. The board includes a narrow tuning range balun, which is performance optimized for 2.4GHz, and provides datasheet specifications.
The AD-FMCOMMS3-EBZ board, in simple terms, is just the AD9361 in a 2 x 2 RF configuration. Hence the features and capabilities of the device extends to the board. The board includes a wide tuning range balun, which is close to datasheet specifications.
The AD-FMCOMMS4-EBZ board, in simple terms, is just the AD9364 in a 1 x 1 RF configuration. Hence the features and capabilities of the device extends to the board. The board includes both a narrow and wide tuning range balun on a multiplexed input/output.
The AD-FMCOMMS5-EBZ board, in simple terms, is two AD9361s in a 4 x 4 RF configuration, which demonstrates how to synchronize multiple devices together. The features and capabilities of the device extends to the board. The board includes both a narrow and wide tuning range baluns on a different SMA connectors.
