MIMO platform for advanced communications and PNT applications

The A2300 is a multiple-input and multiple-output (MIMO) transceiver module incorporating two wideband Field Programmable RF (FPRF) transceivers (300 MHz to 3.8 GHz) from Lime Microsystems, 10-axis accelerometer, gyro, compass and barometer sensors, and a large programmable FPGA capable of over 300 MiB/sec sustained communications with a host processor via USB 3.0 interface. The module’s nine integrated RF path options and low size, weight, and power characteristics contribute to ease of integration and portability.

Accommodating both internal 1 PPM TCXO or external frequency reference, multiple A2300s can be inter-connected via an expansion port and/or UART interface, supporting real-time reception / transmission of 4, 6, 8 or more signals without the need for significant additional hardware. With on-board flash for storing developer customizable firmware and FPGA logic, the A2300 can be configured to operate in a variety of different power profiles, maximizing battery life without requiring a host processor.

Modules supplied by Loctronix will be factory-programmed with only the RF receiver capabilities enabled. Developers can enable transmit functionality by modifying the firmware and waveforms.

A2300 Updates and Making SDR Easier

Updates continue to be made to the A2300 Project to enhance both the platform-independent C/C++ API and support for the GNU Radio tools (via Ettus UHD).  In the next month, we will be uploading the HDL modifications for enabling ASR-2300 transmit functions as well as more open-source firmware updates…
