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¶
TBD
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
RF Output Power¶
TBD
LimeSDR PCIe¶
TBD
OsmoTRX on LimeSDR¶
In terms of OsmoTRX for LimeSDR, we now haveosmo-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]
