Abstract
An oscillator includes: oscillation units (11 through 1n) outputting oscillation signals of different frequencies; a transmission line (15) to which outputs of the oscillation units (11, 12) are connected, the transmission line having a characteristic impedance corresponding to an output impedance of an output terminal (Tout); and a low-pass filter 818) connected between the transmission line (15) and the output terminal.
