LimeSDR is an open source, apps-enabled software-defined radio (SDR) platform that can be used to support just about any type of wireless communication standard; it can transmit and receive UMTS, LTE, GSM, LoRa, Bluetooth, Zigbee, RFID, and Digital Broadcasting, to name but a few.

The LimeSDR platform is comprised of a family of boards that range from a cost optimised 1×1 SISO board and a highly affordable 2×2 MIMO solution — both with USB3.0 interface — up to

  • RF Transceiver: Lime Microsystems LMS7002M FPRF
  • FPGA: Altera Cyclone IV EP4CE40F23 – also compatible with EP4CE30F23
  • Memory: 256 MBytes DDR2 SDRAM
  • USB 3.0 controller: Cypress USB 3.0 CYUSB3014-BZXC
  • Oscillator: Rakon RPT7050A @30.72MHz
  • Continuous frequency range: 100 kHz – 3.8 GHz
  • Bandwidth: 61.44 MHz
  • RF connection: 12x U.FL connectors (6 RX, 4 TX, 2 CLK I/O)
  • Power Output (CW): up to 10 dBm
  • Multiplexing: 2×2 MIMO
  • Power: Micro USB connector or optional external power supply
  • Status indicators: programmable LEDs
  • Dimensions: 100 mm x 60 mm
