Frequency synthesizer for synthesizing signals of a variety of frequencies by cross modulation










Image Number 7 for United States Patent #5559475.

A frequency synthesizer in which a PLL synthesizer 50 generates signals of frequency steps of an integer times a target frequency step. A base band generator 2 digitally generates sine wave signal components of the target frequency step. The outputs from the PLL synthesizer 50 and the base band generator 2 are cross-modulated by use of a quadrature modulator 1 to change the frequency of the output signals with a change step of the base band generator 2.
