Patent ID: 11146298

Abstract:
A signal generator device includes a digital signal waveform generator to produce a digital signal waveform, a first frequency band signal path having a first frequency band filter to receive the digital signal waveform and to pass first frequency band components of the digital signal waveform, and a first digital-to-analog converter to receive the first frequency band components of the digital signal waveform and to produce a first frequency band analog signal, a second frequency band signal path having a second frequency band filter to receive the digital signal waveform and to pass second frequency band components of the digital signal waveform, a second digital-to-analog converter to receive the second frequency band components of the digital signal waveform and to produce a second frequency band analog signal, and a combining element to combine the first frequency band analog signal and the second frequency band analog signal to produce a wideband analog signal. A method of generating a wideband analog signal includes generating a digital waveform, splitting the digital waveform into at least a first frequency band signal and a second frequency band signal, converting the first frequency band signal into a first frequency band analog signal, converting the second frequency band signal into a second frequency analog signal, and combining the first frequency band analog signal with the second frequency band analog signal to produce the wideband analog signal.
