Image Reject Mixers
Single Sideband Modulator is a integrated network consisting of a two double balanced mixers, two 90° quadrature hybrids and a in-phase power divider. The primary function of the circuit is to modulate a carrier such that all energy is in either the upper or lower sideband. Single Sideband Modulator are most widely used in modulating applications, where the RF sidebands are so close in frequency that filtering is impractical. Sirius Microwave offers a line of a multioctave bandwidth Single Sideband Modulators. Also various types of narrowband, octaveband and custom design units available. Contact factory for details here.
Features:
Ultra-wide bandwidth
High image rejection
