Abstract :
This paper reports a compact high power oscillator operating from 2.3 GHz to 2.9 GHz. Its two differential outputs deliver up to 57 W of power with an efficiency peaking at 54 %. A phase noise of -125 dBc / Hz is achieved at 1 MHz offset frequency. The oscillator is realized as a hybrid circuit with two GaN HEMTs. Including the housing, it fits in an area of less than 13 cm2.
