Power amplifiers (PA) are nonlinear devices and their linearisation is highly desired for a number of reasons. In case of radio frequency (RF) PAs, linearisation improves power efficiency and subsequently reduces running cost of the wireless infrastructure. Considering the PA performance for a given air interface, adjacent channel power ratio (ACPR) and error vector magnitude…

The FreeSRP is an open-source (hardware and software) platform for software-defined radio that is affordable, high performance, compatible with existing SDR software such as GNU Radio, and includes an expansion port for hardware add-ons. FreeSRP comes in a small, portable form factor (7 cm x 11 cm) that can be completely powered from USB. FreeSRP…
The pyLMS7002M Python package is platform-independent, and is intended for fast prototyping and algorithm development. It provides low level register access and high level convenience functions for controlling the LMS7002M chip and evaluation boards.
This project is concerned with creating RF front-end modules, such as PAs, LNAs and filters, that can be used together with an SDR platform in order to create a complete wireless solution.
LimeSDR is a low cost, 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.
ClockTamer is a device manufactured by Fairwaves to provide a low-cost small-size configurable clock generator with GPS sync option. It was specifically designed to be used with USRP, but nothing prevents you from using it with other device of your choice given it has external clock input.
STREAM is a flexible platform for developing high-performance digital and RF designs using an Altera Cyclone IV FPGA and Lime Microsystems FPRF transceiver. It is available in its original form factor and a much more compact, lower cost micro variant.
This project contains a C driver for control of the LMS7002M transceiver. The driver provides user APIs for tuning frequencies, setting gains, setting filters, setting sample rates, setting stream modes, configuring switches, and calibration. Although this driver can select the streaming mode of the LMS7002M, it does not directly interact with receive or transmit baseband data.
Lime Suite is a collection of software supporting several hardware platforms including the LimeSDR, drivers for the LMS7002M transceiver RFIC, and other tools for developing with LMS7-based hardware.
This project aims to build a collection of component footprints and models that are useful when designing RF systems.
