    摘要： PROBLEM TO BE SOLVED: To reduce a circuit error between differential output signals when inputting a differential input signal and outputting a pair of differential output signals.SOLUTION: A power division circuit 10 includes transformers 2A, 2B and an addition circuit 3. Output signals of the transformer 2A are output as differential signals comprising a normal phase signal (Vout2Ap) with a phase of θ1+90° and a reverse phase signal (Vout2An) with a phase of θ1-90°. Output signals of the transformer 2B are output as differential signals comprising a normal phase signal (Vout2Bp) with a phase of θ2+90° and a reverse phase signal (Vout2Bn) with a phase of θ2-90°. The addition circuit 3 performs vector additions of the normal phase signals and of the reverse phase signals to combine the two pairs of differential signals from the transformers 2A, 2B into one pair of differential output signals. The differential output signals are signals compensated for a phase error (θ1-θ2) caused in the transformers 2A, 2B.
