<p>The present invention provides a frequency multiplier and a method for generating frequency multiplied signals. The frequency multiplier includes: a first stepped-impedance transmission line configured to receive a first signal of a first differential signal; a second stepped-impedance transmission line configured to receive a second signal of the first differential signal, where the first stepped-impedance transmission line and the second stepped-impedance transmission line superpose 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 line configured to be inversely ground-coupled with the first stepped-impedance transmission line and grounded at an end near an output end of the first stepped-impedance transmission line; a second inverse stepped-impedance transmission line configured to be inversely ground-coupled with the second stepped-impedance transmission line and grounded at an end near an output end of the second stepped-impedance transmission line, where another end of the first inverse stepped-impedance transmission line and another end of the second inverse stepped-impedance transmission line superpose signals to output a second frequency multiplied signal. The present invention allows a frequency multiplier to output differential signals by using two inverse stepped-impedance transmission lines respectively inversely ground-coupled with two stepped-impedance transmission lines.</p> |
