In this paper, a high efficiency power oscillator is designed at C‐band for the applications of wireless power transmission. A harmonic‐tuning technique is adopted to achieve a high efficiency at a high frequency. It is also shown that the efficiency of the oscillator is degraded due to the reduced gain of the semi‐conductor transistor at high frequency. The fabricated oscillator using GaN transistor shows an output power of 38.1 dBm with an efficiency of 58.4% at 5.71 GHz, which corresponds to the excellent performance among the reported oscillators around 5 GHz. © 2016 Wiley Periodicals, Inc.

“…However, the described techniques cannot be directly applied to the design of oscillators, due to fact that the power, the frequency and the stability of the autonomous signal have to be simultaneously controlled. Specific efficiency optimization techniques for microwave oscillators have also been developed [9][10][11][12][13][14][15][16][17][18]. Some of them are applied to optimize fixed frequency oscillators.…”

Abstract-In this work a non-linear efficiency optimization method for its application to an Injection-Locked High Efficiency Voltage Controlled Oscillator is presented. The proposed approach is based on the control of the harmonic content of the oscillator autonomous signal, which is accomplished through the use of an Auxiliary Generator and several multi-harmonic loads based on Arbitrarily Width-Modulated Microstrip Lines. The presented technique has been applied to the design of a 2.5 GHz high efficiency Voltage Controlled Oscillator, which has been manufactured and experimentally characterized, obtaining a good agreement between the simulated and measured results.
