Abstract
A transmitter/receiver () up-converts, using an LO signal as a local oscillation signal, an IF signal having a predetermined frequency band, thereby generating a transmission signal RF. Moreover, the transmitter/receiver () generates a (LO+IF)signal and a (LO−IF)signal based on the IF signal and the LO signal. Using the LO signal obtained by adding-up of the (LO+IF)signal and the (LO−IF)signal, a reception signal RFis down-converted. Thus, a local oscillation signal generation unit of a receiving unit is not necessary.
