Latest Patents

Ryota Fujii holds a patent for a "Modulator and frequency multiplier for use therein." This invention discloses a modulator that effectively suppresses carrier leakage. The modulator includes a frequency multiplier, a phase shifter, and an orthogonal modulator. The frequency multiplier outputs complementary signals whose frequencies are twice that of a first carrier signal. The phase shifter divides the frequencies of the output signals from the frequency multiplier to produce a plurality of second carrier signals, each shifted by 90 degrees in phase. The orthogonal modulator combines the input signal with the second carrier signals to output the final signals. The frequency multiplier features an input circuit section that includes a differential circuit, which receives complementary signals as the first carrier signal. Additionally, the orthogonal modulator has an output circuit section that also includes a differential circuit.
