Rincon Research’s LPFE-IFXR-01 is an eXtreme Software-Defined Radio (xSDR), combining the xSDR LPFE DSP Base Card and xSDR IFXR in a compact chassis. The LPFE-IFXR is a high-performance DSP system, ideal for pairing with microwave receivers or direct-sampling HF signals. Its high-performance dual IF transceiver includes 14 bit, 500 MSPS ADCs and 16 bit, 615 MSPS DACs. This mezzanine card includes filters and amplifiers to simplify interfacing with external receivers and antennas.

The MountainBrik™ application may be used with the LPFE-IFXR to control the transceiver, view signal spectra, and record receiver data. Rincon’s embedded Linux distribution, combined with the MountainBrik firmware, is capable of streaming signal data through the Ethernet interface at over 100 MByte/sec.


  • Wide input bandwidth enables IF digitization and direct-sampling applications from HF to 1 GHz
  • Dual channel 14 bit ADCs, 200 MSPS to 500 MSPS
  • Dual channel 16 bit DACs, 10 MSPS to 615 MSPS
  • Ultra-low jitter integrated clock source, accepts external reference
  • High-performance Xilinx Zynq Z7045 FPGA/ARM SoC
  • Low-power IF-to-packets capability
  • Many applications consume less than 15 W
  • Capable of high-rate, high-order modulations (application not included)
    • FSK, BPSK, QPSK, SQPSK, 8PSK, QAM16 to QAM1024
  • Flexible boot options
    • NFS, microSD card, or RAM-disk
  • Write-protection controls for all non-volatile memory
  • Flexible power options
    • 9 VDC to 57 VDC
    • Power over Ethernet (PoE) Type 2
  • Accepts external time/frequency standards for geo-capable time-tagging
  • Two rugged enclosures available, fan-cooled or conduction-cooled with IP-67 construction
