Application of a new thermal nano-probe based on the changes of electrical resistivity of a nanometer-sized filament with temperature has been presented for the thermal imaging of microwave power active devices. The filament is integrated...

This paper presents the design steps for the fabrication of a hybrid microwave power amplifier -PA- based on fT-doubler technique. The PA is implemented using two 6 W discrete GaN-HEMTs on SiC substrate. The fT-doubler technique is used to enhance...
