PET scan, CT and MRI are almost standard in today’s diagnostics – highly developed and very sophisticated. Although more capable and less cost-intensive, laser-optical diagnosis methods are, up to…
InP-on-BiCMOS integration enables ultra-broadband interconnects
/en/research/research-news/inp-on-bicmos-integration-enables-ultra-broadband-interconnects
The bandwidth available in microwave and milllimeterwave modules is often limited also by the packaging approach and the interconnects between the circuits. It is therefore, usually, restricted to a…
