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. Increase in the number of voltage-controlled oscillators for multiband communication, broadening of the band, and increase in phase noise can be reduced.

摘要： A clearing section includes a counter for measuring a period up to the reset of contents set by means of an operation panel to initial values. If a position discriminating section discriminates that the operation panel is at a first position, the clearing section starts measuring the period by means of the counter from the first entry made to the operation panel. When a count value reaches a predetermined value, the clearing section executes an automatic clear processing to reset the contents set by means of the operation panel to the initial values. On the other hand, the clearing section cancels the execution of the automatic clear processing if the position discriminating section discriminates that the operation panel is at a second position.
