<p>A frequency multiplier (100) and a method of generating a frequency-multiplied signal. The frequency multiplier (100) comprises: a first stepped-impedance transmission circuit (110) for receiving a first signal of a first differential signal; a second stepped-impedance transmission circuit (120) for receiving a second signal of the first differential signal, the first stepped-impedance transmission circuit (110) and the second stepped-impedance transmission circuit (120) superposing the first signal of the first differential signal on the second signal of the first differential signal to obtain a first frequency-multiplied signal; a first inverse stepped-impedance transmission circuit (130) for inverse ground coupling to the first stepped-impedance transmission circuit (110), the first inverse stepped-impedance transmission circuit (130) being close to the ground of one end of an output terminal of the first stepped-impedance transmission circuit (110); a second inverse stepped-impedance transmission circuit (140) for inverse ground coupling to the second stepped-impedance transmission circuit (120), the second inverse stepped-impedance transmission circuit (140) being close to the ground of one end of an output terminal of the second stepped-impedance transmission circuit (120), wherein the other end of the first inverse stepped-impedance transmission circuit (130) and the other end of the second inverse stepped-impedance transmission circuit (140) superpose and output a second frequency-multiplied signal. In the method, a frequency multiplier differential signal is output by means of two inverse stepped-impedance transmission circuits respectively being inverse ground coupled to two stepped-impedance transmission circuits.</p> |
