Abstract
A signal synthesizer circuit includes a clock source, a direct digital synthesizer (DDS) circuit, signal paths, and an output. The clock source generates or receives a clock signal having a predefined frequency. The DDS circuit generates a DDS signal. A first signal path is connected to the DDS circuit to receive the DDS signal and includes a multiplier circuit that multiplies a frequency of the DDS signal by a multiplication factor, obtaining a frequency-multiplied DDS signal. A second signal path is connected to the clock source to receive the clock signal and includes a mixer circuit that receives the clock signal and the frequency-multiplied DDS signal. The mixer circuit mixes the clock signal with the frequency-multiplied DDS signal, obtaining a mixed DDS signal. A frequency of the mixed DDS signal corresponds to the sum of frequencies of the clock signal and the frequency-multiplied DDS signal.
