Abstract:
1. A transceiver comprising: a receiver; and a transmitter, wherein the receiver includes a reception demodulator to down-convert an RF reception signal to a reception analog signal, wherein the transmitter includes a voltage-controlled oscillator for transmission and a plurality of transmission blocks to generate RF transmission signals of a plurality of frequency bands, wherein each of the transmission blocks includes a frequency divider and a modulator for transmission, wherein, in each of the transmission blocks, the frequency divider supplies a pair of transmission local signals generated by dividing a transmission oscillation output signal supplied from the voltage-controlled oscillator for transmission to the modulator for transmission, wherein, in each of the transmission blocks, the modulator for transmission up-converts a transmission analog signal to an RF transmission signal based on the pair of transmission local signals supplied from the frequency divider, wherein, for at least one of the transmission blocks, the frequency divider has a frequency dividing number set to an even-numbered integer, and wherein, for an other transmission block, the frequency divider has a frequency dividing number set to a non-integer.
