Ultra Wide-Band, High-Power, High-Efficiency GaN Amplifier

We report a high-performance GaN amplifier operating from 100MHz to 3,000MHz. The best results included 100W output power, 22dB gain with 40% power- added-efficiency from 100MHz to 3,000MHz. This performance is achieved by tailoring both the device impedance and by using unique wide-band circuit matching topology. Detailed design technique of both device and matching circuit will be presented.
