Abstract
A subharmonically pumped single sideband Schottky diode modulator is described. Its advantages are a large carrier suppression and Iowered pumping frequency. The experimental 2-GHz MIC modulator pumped with an 8-mW signal exhibits a conversion loss of 6.2-7.3 dB over a 15-percent frequeney band. For a 120-mu W input modulating signal, the unwanted components in the output spectrum are at least 18 dB and mostly over 20 dB below the desired sideband.
