Abstract :
Summary form only given, as follows. This paper proposes a new configuration for power oscillators based on the combined power amplifier. The focus is on power combining as a oscillator structure with a positive feedback loop line. The measured output power and conversion efficiency of the proposed oscillator are 46.8 dBm and 58 %, respectively, at 2.45 GHz with an applied drain bias voltage of 28 V.
