ABSTRACT:
An power divider and a surface acoustic wave resonator are provided to a feedback path of an amplifier for oscillation. The surface acoustic wave resonator connects an input side of the amplifier and the power divider connects an output side of the amplifier so as to suppress an input power input to the surface acoustic wave resonator and to secure an output power output from an output terminal of the power divider.
