RFTool is a standalone AD9361 based SDR with a USB 3 interface and a number of other useful features:
- AD9361 transceiver IC - dual channel 70MHz-6GHz, up to 54MHz channel bandwidth
- Xilinx Artix-7 FPGA (XC7A50T-2FTG256I) with 64MBit HyperRAM
- FT601Q USB 3.0 interface
- Two LNA inputs (500MHz-3GHz only) and one attenuated input (full AD9361 range)
- All inputs protected to over +27dBm input
- Two PA outputs (500MHz-3GHz only) with >20dBm output power and one direct output (full range)
- Flexible external reference input (switchable termination and coupling)
- USB powered, no external power needed
Rev 1.0 of the hardware has been built and initial tests completed. Receive-only FPGA code and a simple Spectrum Analyser application for Linux has also been built.
