Marki Amplified doublers integrate one or two low noise amplifiers with a schottky diode doubler ring, ideal for low phase noise applications. They offer excellent conversion efficiency across multi-octave bandwidths to 50 GHz, with good fundamental and odd harmonic suppression. As with all multipliers and mixers, it is important to drive amplified doublers with the recommended drive level.
