  • Patent number: 10187092
    Abstract: In a digital transmitter, a digital RF signal generation unit executes digital modulation on I and Q signals to convert the I and Q signal into first and second digital RF signals, respectively, with a bit rate which is twice a carrier frequency. A retiming unit delays the first digital RF signal according to a clock signal with a frequency which is 4n times (n is an integer) the carrier frequency to output the delayed first digital RF signal and delays the phase of the second digital RF signal by 90 degrees with respect to an output of the first digital RF signal to output the delayed second digital RF signal. First and second amplifiers amplify the first and second digital RF signals output by the retiming unit, respectively.
