1. A phase shift method, comprising:
shifting phase of an input signal by a phase shifter; and
up-converting frequency of the input signal with shifted phase by a multiplication coefficient N by a frequency multiplier,
wherein phase resolution (°) of the phase shifter is determined by

OG Complex Work Unit Math
wherein n represents phase resolution (bits) of the phase shifter, and x represents a number of shifted phase states.
