Abstract
Disclosed is a frequency multiplication apparatus including a first frequency multiplier receiving a first signal having a first frequency and outputting a second signal having a second frequency by multiplying the first frequency by ‘n’ (‘n’ being a positive integer), a second frequency multiplier receiving the second signal and outputting a third signal having a third frequency by multiplying the second frequency by ‘m’ (‘m’ being a positive integer), and a coupler connected between an output of the first frequency multiplier and an input of the second frequency multiplier and outputting a part of the second signal.
