Title:
FREQUENCY CONVERTER
Document Type and Number:
WIPO Patent Application WO/2019/244271
Kind Code:
A1
Abstract:
A frequency converter is provided with: frequency conversion elements 1 to 4 that perform voltage-current conversion on an RF signal, perform frequency conversion by use of an LO signal and output an IF signal; a DC potential detection circuit 20 that detects the DC potentials of the frequency conversion elements 1 to 4; and a bias generation circuit 21 that, on the basis of the DC potentials detected by the DC potential detection circuit 20, generates bias voltages to be applied to the frequency conversion elements 1 to 4, wherein, according to increases of the DC potentials detected by the DC potential detection circuit 20, the bias generation circuit 21 increases the bias voltages.
