Abstract:
1. A wireless circuit which is capable of simultaneously outputting a plurality of transmission signals, comprising: a determination section which determines, out of a plurality of transmission signals that are simultaneously outputted by the wireless circuit, a detecting object signal whose transmission power is to be detected; a selection section to which the plurality of transmission signals are supplied and which selectively outputs the detecting object signal determined by the determination section; and a detection section which detects a power of the detecting object signal which has been outputted by the selection section, the plurality of transmission signals are supplied to the selection section while being coupled to each other; the selection section including a cancellation signal generating section that generates, from the plurality of transmission signals, a cancellation signal which cancels each of the plurality of transmission signals, the selection section selectively outputting the detecting object signal, by adding, to the plurality of transmission signals which have been supplied to the selection section while being coupled to each other, the cancellation signal which (i) has been generated by the cancellation signal generating section and (ii) cancels a transmission signal which differs from the detecting object signal.
