Title:
FREQUENCY CONVERTER, MEASURING SYSTEM, AND MEASURING METHOD
Document Type and Number:
WIPO Patent Application WO/2016/136947
Kind Code:
A1
Abstract:
A frequency converter which accepts as inputs a prescribed input signal and a prescribed local oscillation signal, and outputs as an output signal a signal in which the input signal is mixed with a harmonic signal having a frequency n times the frequency of the local oscillation signal, wherein a circuit which mixes the input signal and the harmonic signal is a harmonic mixer (11) which uses a nonlinear characteristic of a semiconductor element to mix the harmonic signal and the input signal, and wherein the input signal or the output signal is subjected, either before input into the frequency converter or after output from the frequency converter, to correction on the basis of the amplitude and phase frequency characteristics of the frequency converter, which have been measured in advance.
