6 results about "Harmonic mixer" patented technology

The harmonic mixer and subharmonic mixer are a type of frequency mixer, which is a circuit that changes one signal frequency to another. The ordinary mixer has two input signals and one output signal. If the two input signals are sinewaves at frequencies f₁ and f₂, then the output signal consists of frequency components at the sum f₁+f₂ and difference f₁−f₂ frequencies. In contrast, the harmonic and subharmonic mixers form sum and difference frequencies at a harmonic multiple of one of the inputs. The output signal then contains frequencies such as f₁+kf₂ and f₁−kf₂ where k is an integer.
