Lime backs Lattice for software defined radio board
Lime Microsystems in the UK is preparing to launch a successor to the popular LimeSDR Mini open-source software defined radio using an FPGA from Lattice Semiconductor.
The new version, to be launched on Crowd Supply, uses a larger field-programmable gate array (FPGA) for projects looking to perform operations on-device and ease the load on the host processor.
- Raspberry Pi and LimeSDR open-source DVB project
- LimeSDR platform gets an app store
- 4G core network app available for LimeNET, LimeSDR
- Open source 5G in a box uses 16 core AMD processor
原始Limesdr Mini于2017年推出，基于LimESDR USB，基于相同的LMS7002M现场可编程射频（FPRF）芯片，但仅具有单通道全双工操作而不是双通道全双工操作而不是双通道通道全双工操作。
The LimeSDR Mini 2.0 retains the same LMS7002M that handles a range of 10MHz to 3.5GHz with 40MHz RF bandwidth but moves from the Intel MAX 10 FPGA to a Lattice Semiconductor ECP5m increasing the number of programmable logic gates on-board from 16k to 44k.
This allows a range of workloads to run directly on-device by customising the open-source gateware that is available to all users. This includes adding signal detection capabilities, noise-reduction processing, or filtering.
Elsewhere, the specifications of the new board remain the same – matching feature-for-feature the radio functionality of the original LimeSDR Mini, including its support for operation between 10 MHz and 3.5 GHz, full-duplex reception and transmission, 40 MHz of radio-frequency bandwidth, and a USB 3.0 interface to a host device.
The project ison Crowd Supply.
