The LimeSDR from Lime Microsystems is a Software-Defined Radio (SDR) that operates from 100 kHz to 3.8 GHz. It employs a Lime Microsystems LMS7002M MIMO FPRF chipset, has a bandwidth of 61.44 MHz and supports 2x2 MIMO multiplexing. This low-cost, open-source SDR integrates the Snappy Ubuntu Core to enable easy download of LimeSDR apps from developers around the world. It uses the Altera Cyclone IV EP4CE40F23 FPGA, 256 MB DDR2 SDRAM and a Rakon RPT7050A @30.72 MHz oscillator. This radio is available in a PCB form factor that measures 100 x 60 mm with 10x U.FL RF connectors and has programmable LED status indicators. It can be powered via a micro-USB interface or an optional external power supply.
The LimeSDR is suitable for use in various applications including radio astronomy, RADAR, 2G to 4G cellular base stations, media streaming, IoT gateway, HAM radio, wireless keyboard and mice emulation and detection, tire pressure monitoring systems, aviation transponders, utility meters, drone command and control and test and measurement.
