发明名称 Transceiver
摘要 A transceiver includes an oscillator and a plurality of communication blocks. Each of the communication blocks includes frequency dividers and mixers. Frequency dividing number of the frequency divider included in one communication block is set to an even-numbered integer, and transmission local signals supplied from the frequency dividers to the mixer become quadrature signals having a phase difference of 90 degrees. The frequency dividing number of another frequency divider in the another communication block is set to a non-integer, and communication local signals supplied from the frequency divider to the mixers become non-quadrature signals having a phase difference at a predetermined offset angle from 90 degrees. The transceiver further includes a converting unit for giving a compensation offset amount having almost the same absolute value and having a polarity opposite to that of the offset angle to communication analog signals related to the mixer of the another communication block.
