160W InAlN/GaN HEMTs amplifier at 2 GHz with optimized thermal management

Résumé

We report on the realization and measurements of InAlN/GaN HEMTs on SiC substrate. At device level, load-pull power measurements were performed at 2 GHz on 2.2mm devices in CW mode. An output power of 10.5W (40.2dBm) with a PAE of 53% were reached. Then, an amplifier was realized using 36mm power die. Thanks to an optimized thermal management, the amplifier allows us to reach an output power of 160W in pulse mode and 105W in CW. To our knowledge, these results represent the highest output powers ever reported for InAlN/GaN HEMT technology.
