Abstract:
A signal generator for providing a data signal on an output signal, comprising:an oscillator configured to provide the output signal; a phase locked loop configured to receive the output signal and to provide a tuning signal to the oscillator, the phase locked loop further comprising: a frequency divider configured to receive the output signal, to divide the output signal, and to provide a divided output signal; a mixer configured to mix the divided output signal with a standard signal and to provide a mixed signal; a phase detector configured to receive the mixed signal, to compare the mixed signal to a reference signal, and to provide the tuning signal to the oscillator based on the comparison; and a fractional divider outside of the phase locked loop configured to receive the data signal, to modulate the data signal on to the reference signal, and to provide the reference signal to the phase detector, wherein the data signal is modulated onto the output signal.
