Abstract: PURPOSE: A wideband voltage controlled oscillator using a varactor drive spilt ring resonator and a microstrip transmission line is provided to supply a DC voltage to the oscillator stably by removing a ripple in an input DC voltage by a voltage stabilizer. CONSTITUTION: A resonation part(110) includes a pair of resonators and determines the oscillation frequency of an output signal. At least one pair of resonators are arranged to face each other while interposing a microstrip transmission line. A plurality of bias units(120) are electrically connected to the front end and the rear end of the transistor connected between the resonator part and the output port. A plurality of voltage stabilizers(130) stabilize the DC voltage inputted from the outside and supply the stabilized DC voltage to the bias unit. A plurality of negative resistors are electrically connected to the terminal which is not connected to the bias unit. The negative resistor generates the output signal of the oscillation frequency band determined in the resonation part.
