Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, a low phase noise positive feedback Push-Push oscillator using a frequency doubler integrated in an injection circuit is proposed. The proposed oscillator consists of a positive feedback Push-Push oscillator and a frequency doubler. In this oscillator, the frequency of the injection signal is the quarter of the output frequency, thus the phase noise of the high frequency oscillator can be improved by injecting a low frequency signal with low cost. From the measurement results, the phase noise characteristics were improved by using the injection signal.
