SFM series single sideband modulators are GaAs beam lead Schottky diode- or MMIC device-based frequency converters that use the IF frequency as a pumping source. The IF quadrature hybrid is not included in these modulators. Instead, separate I and Q ports are provided. Thus, either an external IF quadrature hybrid or two IF orthogonal, equal amplitude signals are required in order to produce a single sideband signal. The below offering covers the frequency range of 18 to 100 GHz with a typical image rejection of 20 dB, however, additional models can be offered to cover 18 to 110 GHz. The below standard models are designed for narrow bandwidth operations with specific package designs to address common industry requirements. However, custom models can be offered to meet differing application needs.
