Abstract :
High-power GaN-based flip-chip ICs are demonstrated using AlGaN/GaN High-Electron-Mobility-Transistors (HEMTs) as the active devices and AlN as the circuit substrates. The circuits achieved 6-10 GHz bandwidth, 9 dB linear gain and 14.1-W output power. This power level is the highest for a GaN-based amplifier to date, and is a factor of 4-7 higher than conventional GaAs-HEMT-based amplifiers using the same size of output devices.
