Abstract: Frequency multipliers (300) for generating a differential output signal from a single-ended input signal are disclosed. The frequency multiplier comprises a single-ended input (Pin(f0)) to receive the input signal with a frequency of f0 and differential outputs (+/-Pout(2nf0)) to provide the differential output signals. The frequency multiplier further comprises a first signal branch (301) connected to the single-ended input and one of the differential outputs (+Pout(2nf0)). The first signal branch comprises a first low pass or bandpass filter with a center frequency of f0 (L/BPF1), a first nonlinear component (NC1) and a first high pass or bandpass filter with a center frequency of 2nf0 (H/BPF1). The frequency multiplier further comprises a second signal branch connected to the single-end input and another one of the differential outputs (-Pout(2nf0)). The second signal branch comprises a second low pass or bandpass filter with a center frequency of f0 (L/BPF1), a second nonlinear component (NC2) and a second high pass or bandpass filter with a center frequency of 2nf0 (H/BPF2). The first and second nonlinear components are configured such that even-order harmonics generated in the first and second nonlinear components are in anti-phase, thereby the differential output signals with a frequency of 2n times the frequency of the input signal are generated at the differential output, where n is an integer number.

Abstract: A frequency multiplier (200) generates an output signal with a frequency 3 times of the input signal frequency. The frequency multiplier (200) comprises four cascaded stages. A first stage (201) is configured to receive an input signal and generate harmonics signals of the input signal. A second stage (202) is a passive filter, a frequency response of the passive filter has either a peak or a dip around an upper frequency end of a frequency band of the input signal. A third stage (203) is configured to mix the 1st and the 2nd order harmonics signals to generate 3rd order harmonic signals. A fourth stage (204) is configured to supress the 1st and even-order harmonics signals and output a signal dominated with a frequency 3 times of the input signal frequency.
