Abstract
A low-powered mixer that is operable at a low voltage by a single positive power supply. A predetermined voltage and a first data signal Ss1 superimposed on the predetermined voltage are input into the drain D of an FET Q1, while a first carrier signal Sc1 is input into the FET Q1's gate G. The FET Q1 thus generates a first mixed signal So1 by mixing the first data signal Ss1 and the first carrier signal Sc1. A predetermined voltage and a second data signal Ss2 superimposed on the predetermined voltage are input into the FET Q2's drain D, while a second carrier signal Sc2 is input into the FET Q2's gate G. The FET Q2 thus generates a second mixed signal So2 by mixing the second data signal Ss2 and the second carrier signal Sc2. A capacitor C5 causes the sources S of the FETs Q1 and Q2 to float for DC and to be grounded for AC.
