Abstract
A voltage and a data signal superimposed on the voltage are input to the drain of an FET and a carrier signal is input to the gate of the FET. The FET mixes the data signal and the carrier signal to generate the mixed signal. Two capacitors are connected between the source and ground for blocking direct current and passing alternating current.
Claims8
A mixer for mixing a carrier signal and a data signal, comprising:
- an FET for mixing said carrier signal and said data signal which is capable of generating a mixed signal by receiving a voltage and said data signal which is superimposed on said voltage via the drain of said FET and by receiving said carrier signal via the gate of said FET;
- and
- at least one capacitive device connected between the source of said FET and ground for blocking direct current and for passing alternating current.
