ABSTRACT:
A bi-phase modulator including a driver and a mixer. The driver includes a prescaler having an input for receiving a signal and an output for outputting a baseband signal. The mixer includes a mixer having an input coupled to the output of the prescaler for receiving the baseband signal output by the prescaler. The baseband signal output by the prescaler drives the mixer so as to output a modulated waveform from an output of the mixer.
