Abstract
A resonant circuit includes a choke coil, a variable-capacitance diode, coupling capacitors, a resonant capacitor, a resonator defining an inductor element, and a bypass capacitor. An amplifying circuit includes a buffer amplifying transistor, an oscillating transistor, bias resistors, Colpitts capacitors, bypass capacitors, a coupling capacitor, a choke coil, a resonant capacitor, and a resonant inductor. A bias resistor has one end electrically connected to the base of the oscillating transistor and has the other end electrically connected to the ground via the resonator having one end electrically grounded.
