Image Reject Mixers

Image Reject Mixer 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 separate a desired signal from its image signal. Image Reject Mixers are most widely used in receiving applications, when the real and image frequencies are very close (intermediate frequency is low) so that a filtering is impractical. Sirius Microwave offers a line of a multioctave bandwidth Image Reject Mixers. Various types of narrowband, octaveband and custom design units available. For Image Reject Mixers having ultra-wide IF performance look at Fixed LO Image Reject Mixers.
