DARPA November 23, 2022 Technologies for Heat Removal in Electronics at the Device Scale (THREADS) aims to overcome the thermal limits inherent to internal circuitry operations in general, and to critical power-amplifying functions specifically. THREADS targets thermal management challenges at the transistor level. Central to this effort will be reducing the thermal resistance involved in dissipating internal heat without degrading performance or increasing the footprint of the transistors key to advancing radar capabilities. Wide bandgap transistors, such as gallium nitride (GaN), were developed specifically to improve output density in power amplifiers and further order-of-magnitude increase in power output is possible […]
