Abstract
A transformer (A) outputs differential signals of a positive phase signal (VoutAp) having phase θ1+90° and a negative phase signal (VoutAn) having phase θ1−90°. A transformer (B) outputs differential signals of a positive phase signal (VoutBp) having phase θ2+90° and a negative phase signal (VoutBn) having phase θ2−90°. An adding circuit () composes a pair of differential output signals, as signals corrected in phase error (θ1−θ2) generated in the transformers (A,B), in a manner of summing up vectors of two pairs of the differential signals outputted from the transformers (A,B) for the positive phase signal and the negative phase signal, respectively.
