Abstract
A high frequency oscillator has a high frequency generation part, an oscillation part, a matching unit, rectification element parts and switch parts. The oscillation part oscillates high frequency power generated by the high frequency generation part. The matching unit is arranged between the high frequency generation part and the oscillation part, and has one or more capacitors and matching circuits having difference characteristics so as to perform matching between the high frequency generation part and the oscillation part. The rectification element parts and the matching circuits are arranged in one-to-one correspondence. The rectification element parts rectify high frequency power supplied from the high frequency generation part to the oscillation part. The switch part is connected to the corresponding rectification element part to switch the corresponding capacitor connected to the corresponding matching circuit through the corresponding rectification element part.
