Abstract
An oscillator includes an oscillator circuit which includes an oscillator transistor and a resonant circuit. The oscillator circuit can change an oscillation frequency. An amplifier circuit receives an oscillation signal output from the oscillator circuit and amplifies the oscillation signal. The resonant circuit is connected at high frequencies between the base and the collector of the oscillator transistor. The oscillation signal is output from the resonant circuit.
