Rincon Research Corporation’s (RRC) LPFE-RFXR is becoming deprecated. It is a software-defined radio (SDR) system, combining the xSDR LPFE DSP Base Card and the xSDR RFXR into a compact chassis. Its 2×2 MIMO RF transceiver is based on Analog Devices AD9361 to achieve high performance without the need for external filters or LNAs. Tunable from 70 MHz to 6 GHz with up to 56 MHz signal bandwidth, it is ideal for low-power RF front end applications.

The MountainBrik™ application may be used with the LPFE-RFXR to control the receivers, view signal spectra, and record receiver data. RRC’s unique MountainBrik firmware provides nanosecond-accurate time tags regardless of the sample rate. RRC’s embedded Linux distribution, combined with the MountainBrik firmware, is capable of streaming signal data through the Ethernet interface at over 100 MByte/sec.

The board support package (BSP) includes example HDL code and Vivado project and constraints files. The BSP code can be used to implement a simple transponder function where receiver data is looped-back inside the FPGA to the transmitters.
