Abstract:
A device includes a frequency multiplier circuit to receive a base frequency signal, multiply the base frequency signal, and output the multiple of the base frequency signal, and includes an offset frequency generator, including at least one logic gate, to receive the multiple of the base frequency signal and output an offset frequency signal from the at least one logic gate combination. A mixing circuit receives the offset frequency signal and a digital data signal, converts the digital data signal into an analog representation of the digital data signal, and mixes the offset frequency signal and the analog representation of the digital data signal to produce a mixed signal. The device yet further includes a power amplifier to amplify the mixed signal and output the amplified mixed signal as an output frequency signal of the device.
