Abstract :
An X-band low phase noise AlGaN-GaN HEMT MMIC push-push oscillator is designed, fabricated, and characterized. The oscillator is based on two common gate Colpitts oscillators. A minimum phase noise of -101 dBc at 100 kHz offset is achieved. The MMIC was fabricated in an ´in-house process´ at Chalmers University of Technology.
