AD-FMCOMMS1-EBZ
FPGA Mezzanine Card for Wireless Communications
Product Detail
The AD-FMCOMMS1-EBZ high-speed analog module is designed to showcase the latest generation high-speed data converters. The AD-FMCOMMS1-EBZ provides the analog front-end for a wide range of compute-intensive FPGA-based radio applications.
The AD-FMCOMMS1-EBZ is an analog front end hardware platform that addresses a broad range of research, academic, industrial and defense applications. The AD-FMCOMMS1-EBZ enables RF applications from 400MHz to 4 GHz. The module is customizable to a wide range of frequencies by software without any hardware changes, providing options for GPS or IEEE 1588 Synchronization, and MIMO configurations.
When combined with the Xilinx ZYNQ® Software-Defined Radio Kit, AD-FMCOMMS1-EBZ enables a variety of wireless communications functions at the physical layer, from baseband to RF. With up to 4 GB of flash storage space, 512 MB of RAM, Gigabit Ethernet interface (depending on the base platform) and a Linux image built specifically for the AD-FMCOMMS1-EBZ, you can get everything you need for a easy out of the box experience. The platform offers enough flexibility for many applications, and supports streaming data, and standard web interfaces to analyze transmitted RF data.
Applications
- Electronic test and measurement equipment
- General-purpose software radios
- Radar systems
- Ultra wideband satellite receivers
