Abstract
Frequency multipliers () for generating a differential output signal from a single-ended input signal are disclosed. The frequency multiplier comprises a single-ended input (P(f)) to receive the input signal with a frequency of fand differential outputs (+/−P(2nf)) to provide the differential output signals. The frequency multiplier further comprises a first signal branch () connected to the single-ended input and one of the differential outputs (+P(2nf)). The first signal branch comprises a first low pass or bandpass filter with a center frequency of f(L/BPF), a first nonlinear component (NC) and a first high pass or bandpass filter with a center frequency of 2nf(H/BPF). The frequency multiplier further comprises a second signal branch connected to the single-end input and another one of the differential outputs (−P(2nf)). The second signal branch comprises a second low pass or bandpass filter with a center frequency of f(L/BPF), a second nonlinear component (NC) and a second high pass or bandpass filter with a center frequency of 2nf(H/BPF). 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.
