Claim 6:
7. The digital RF transmitter of claim 6, wherein
the plurality of clock signals include first clock signals having a phase of 0 degree, second clock signals having a phase of 45 degrees, third clock signals having a phase of 90 degrees, fourth clock signals having a phase of 135 degrees, fifth clock signals having a phase of 180 degrees, sixth clock signals having a phase of 225 degrees, seventh clock signals having a phase of 270 degrees, and eighth clock signals having a phase of 315 degrees, and
the processing circuitry is configured to
generate the first pattern signals by first-multiplying the first clock signals by the I binary data, the third clock signal by the Q binary data, the fifth clock signal by the inverted I binary data, and the seventh clock signal by the inverted Q binary data and summing results of the first-multiplying,
generate the second pattern signals by second-multiplying the second clock signals by the I binary data, the fourth clock signal by the Q binary data, the sixth clock signal by the inverted I binary data, and the eighth clock signal by the inverted Q binary data and summing results of the second-multiplying, and
generate the third pattern signals by third-multiplying the third clock signals by the I binary data, the fifth clock signal by the Q binary data, the seventh clock signal by the inverted I binary data, and the first clock signal by the inverted Q binary data and summing results of the third-multiplying.
