Abstract : This patent discloses a double sideband suppressed carrier modulator apparatus for combining two serrodyne (i.e., single sideband) modulators to achieve double sideband, suppressed carrier modulation. An RF input signal is divided into two carrier signals which are 90 degrees out of phase and applied to the serrodyne modulator units. The modulated signals from the modulators are combined in a 90 degree power divider to provide a double sideband suppressed carrier modulated output signal.
