IMS Radio lab is focused on developing and researching radio frequency systems. We have experience with radio frequency system and circuit design, software defined radio and embedded design. From radio system side we have capabilities to analyse, design and characterize RF amplifiers, switches and other circuits. We have extensive knowledge on GNU Radio software defined radio platform and other signal analysis and processing tools. We also have complementary embedded and mechanical design competences.
Our lab has equipment to design and measure radio circuits up to 8.5 Ghz. We have vector network analysers, spectrum analysers, signal generators. For general embedded design our lab has source measurement unit, oscilloscopes, power supplies and precision multimeters. From quick prototyping and iteration side we have soldering and reworking workplaces, PCB milling capabilities and 3D printers.
