SDR RADIO FRONT-END MIMO – 8 TRX
SDR RADIO FRONT-END MIMO – 8 TRX
The document provides an overview of the Software Defined Radio (SDR) platform developed by the Fraunhofer Heinrich Hertz Institute. This platform is designed for flexible radio communication applications, supporting multiple transceivers and high-speed data interfaces.
Specifications
The SDR platform features a flexible design with 2, 4, or 8 transceivers and supports a wide range of carrier frequencies from 70 MHz to 6 GHz. It includes a 4 x 10Gbps optical baseband interface with a QSFP connector and a 1 Gb Ethernet interface. The platform is built in an AMC form factor and supports various communication standards with variable signal bandwidths, carrier frequencies, and transmit power.
Features
The platform supports multiband, MIMO, and beamforming operations, with configurations for 2x2, 4x4, or 8x8 MIMO duplex operation. It is capable of FDD and TDD operations and supports all LTE bands. The system includes a variable bandpass RF filter and supports CPRI 4.1, OBSAI, and 10GbE standards.
Applications
The SDR platform is suitable for 5G prototyping, allowing for arbitrary waveforms and Multi-MIMO configurations. It is designed for use in both mobile and fixed broadband communication networks and multimedia systems.
Technical Details
The platform utilizes Xilinx Zynq-7000 FPGA with a Linux operating system. It features RX & TX LOs referenced on a recovered optical interface CLK or an external CLK reference, ensuring fully synchronized RF and baseband oscillators. The baseband optical data rate can reach up to 4x 10 Gbit/s, and the system includes 1 GByte DDR3 SDRAM and 64MByte Flash memory.
Analog Design
The analog design incorporates AD9361 RF Transceivers with integrated ADCs/DACs, supporting a carrier frequency range of 70 MHz to 6 GHz and an analog bandwidth of 200 KHz to 56 MHz. The noise figure is less than 2.5dB, and the maximal output power is 0 dBm at 2.6 GHz. External power amplifiers and duplex components like SAW filters, diplexers, and TDD switches are available depending on the carrier frequency.
