LimeSDR USB

The LimeSDR is a low-cost SDR board featuring the Lime Microsystems LMS7002 RF chip.

Key characteristics include:
  • RF Transceiver: Lime Microsystems LMS7002M MIMO 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: 10 U.FL connectors (6 RX, 4 TX)
  • 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

RF Output Power

TBD

Clock

The on-board clock is a 250ppb VCTCXO. GSM strictly requires 30ppb, but 250ppb should be sufficient for laboratory use.

Clock Calibration

TBD

Using external clock reference

LimeSDR Mini

The LimeSDR Mini is a smaller, less expensive version of the original LimeSDR.

Key characteristics include:
  • RF Transceiver: Lime Microsystems LMS7002M FPRF
  • FPGA: Altera MAX 10 (10M16SAU169C8G)
  • EEPROM memory: 2 x 128 KB for RF transciever MCU firmware and data
  • Flash memory: 1 x 4 MB flash memory for data
  • USB 3.0 controller: FTDI FT601
  • Rakon 30.72 MHz VCTCXO
  • Continuous frequency range: 10 MHz – 3.5 GHz
  • Bandwidth: 30.72 MHz
  • RF Connection: 2 x SMA connectors (each can be switched between high and low frequency bands) + 1x U.FL REF CLK
  • Power Output (CW): up to 10 dBm
  • Dimensions: 69 mm x 31.4 mm

OsmoTRX on LimeSDR

In terms of OsmoTRX for LimeSDR, we now have osmo-trx-lms which avoids the previously complex driver stack with UHD, SoapyUHD, SoapySDR, etc. All you need in terms of dependencies is:
  • LimeSuite containing the actual drivers and utilities for LimeSDR (version 17.09 or later required)
    • for LimeSDR-mini, you will need 17.10 or later

Verifying the driver stack

You can ensure that LimeSuite recognizes your device using the LimeUtil part of LimeSuite:

$ LimeUtil --find
  * [LimeSDR-USB, media=USB 3.0, module=STREAM, addr=1d50:6108, serial=0009060B00xxyyzz]
