ABSTRACT:
An oscillating circuit includes a resonator for outputting a signal, an amplifier for amplifying the signal output from the resonator, and a radiator for transmitting a radio wave by resonating the signal amplified by the amplifier. The amplifier has a transistor connected to the resonator and a fixed inductor applying an alternating current load to the transistor. The transistor outputs a signal to be adjusted by the fixed inductor to finely adjust the frequency of the radio wave.
