The high breakdown voltage and current handling capability of GaN HEMTs enable a 10x increase in RF power over conventional GaAs- based devices for the same device size. These benefits translate to dramatically improved performance for military and commercial communications, radar and high-power RF systems. However, despite the high thermal conductivity materials and optimized epitaxial profiles already being used, additional improvement of MMIC performance is limited by thermal constraints. Substrate and near channel thermal resistance is a key thermal bottleneck limiting device compaction and junction temperature reduction. NGAS will report on revolutionary methods being developed to directly integrate high quality, high thermal conductivity diamond materials with more than 4x greater thermal conductivity over existing state-of-the-art GaN on SiC HEMT technology.

A systematic design methodology was used to optimize the size and complexity of the frequency agile DPA thus locating the reconfigurability out of the combining network so that this latter can be kept off-chip. A monolithic DPA was designed and fabricated using the Canadian Photonics Fabrication Centre GaN500 monolithic microwave integrated circuit (MMIC) process (0.5 um gate length) which was operated at 1.7GHz, 2.14GHz and 2.6GHz.
