Title:
SIGNAL GENERATION DEVICE AND WIDEBAND ANALOG SIGNAL GENERATION METHOD
Document Type and Number:
Japanese Patent JP2020120374
Kind Code:
A
Abstract:
To generate an analog signal with a wider bandwidth.SOLUTION: A signal generation device 10 includes a digital signal waveform generation unit 12 that generates a digital signal waveform. A low frequency (LF) signal path includes a low pass filter 16 that receives a digital signal waveform and passes a LF component of the digital signal waveform, and an LF DAC 22 that receives the LF component and generates an LF analog signal. A high frequency (HF) signal path includes a high pass filter 26 that receives a digital signal waveform and passes a HF component of the digital signal waveform, and a second DAC that receives the HF component and generates an HF analog signal. A mixing element 40 mixes the LF and HF analog signals to generate a wideband analog signal.SELECTED DRAWING: Figure 1
