供給するレベル調整器とを含む自動位相補正回路。a variable phase shifter that receives an input signal and adjusts its phase in accordance with a predetermined control voltage; a phase fluctuation detector that receives the output of the variable phase shifter and detects phase fluctuations of the input signal; a counting controller that generates a control signal to compare the output of the output with a predetermined threshold, stop counting when the output is within the threshold, and increase or decrease the count when the output is outside the threshold, and a predetermined clock. A counter whose counting is controlled by the control signal from the counting controller is stored in association with the counting output of this counter and related parameters, and the output is stopped when the counting control signal is within a threshold value. However, in other cases, a non-volatile memory that outputs the output of the counter as is, an A/D converter that converts the output of this memory into an analog value, and a level adjustment of the output of this A/D converter to perform the control. an automatic phase correction circuit including a level adjuster for creating a voltage and supplying it to the variable phase shifter.
