  • Transmitter/receiver and signal generation method
    Patent number: 11616527
    Abstract: A transmitter/receiver (1) up-converts, using an LO signal as a local oscillation signal, an IF signal having a predetermined frequency band, thereby generating a transmission signal RFTX. Moreover, the transmitter/receiver (1) generates a (LO+IF)2 signal and a (LO?IF)2 signal based on the IF signal and the LO signal. Using the LO signal obtained by adding-up of the (LO+IF)2 signal and the (LO?IF)2 signal, a reception signal RFRX is down-converted. Thus, a local oscillation signal generation unit of a receiving unit is not necessary.
