Abstract: A frequency tuning apparatus includes: a frequency tuner configured to tune an oscillation frequency of an oscillator based on target information extracted from a mapping table in correspondence to a target frequency, and oscillation information collected from the oscillator; and a frequency compensator configured to compensate for a compensation error between the tuned oscillation frequency and the target frequency based on an offset table.
