Optical Single Sideband modulation of RF signals at 2 GHz has been experimentally observed. The signal was driven into a microwave circuit that incorporates a quadrature hybrid and a bias network and redirected to a dual-drive Mach-Zehnder modulator. The design of the microwave circuit by using commercial ADS software is presented, as well as the resulting sideband rejection ratio of 20 dB recorded through heterodyne spectrum measurements of the optical modulated signal.
