Abstract: The disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as long term evolution (LTE). An operation method of a device for upconversion in a wireless communication system is provided. The method includes receiving a first local oscillator (LO) signal, generating a second LO signal, based on the first LO signal and cross-coupled latches, receiving an input signal, generating an upconverted frequency, based on the second LO signal and the input signal, generating an output signal obtained by processing a harmonic component included in the upconverted frequency, and transmitting the generated output signal.

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.
