    Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system or a 6th-Generation (6G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system. A frequency multiplier of a wireless communication system is provided. The frequency multiplier includes an input circuit to which a local oscillator (LO) signal is input, a multiplier circuit having one end connected to the input circuit and another end connected to a lower terminal of a load circuit, a load circuit having an upper terminal connected to a voltage controller, and a voltage controller configured between the upper terminal of the load circuit and an input power source, wherein the voltage controller may be configured to drop a voltage between the input power source and the upper terminal of the load circuit and reinput a feedback voltage based on an upper terminal voltage of the load circuit to the voltage controller, and a method of multiplying a frequency using the same.
