Triple-Balanced Mixers are especially valuable for translating large bandwidth segments from one frequency range to another with low intermodulation distortion. The high IF-to-LO and IF-to-RF isolation of this class of mixers makes the conversion loss flatness much less dependent on IF frequency mismatches that almost always exist at the RF and LO ports.
Recently MITEQ perfected a triple-balanced 4 to 40 GHz RF/LO mixer with a 0.5 to 20 GHz IF (Model TB0440LW1). Many customers are using this mixer with several fixed LO's to downconvert the 26 to 40 GHz portion of the millimeter band into existing receivers in the 0.5 to 18 GHz range. This mixer is also useful for upconverting the 0.5 to 18 GHz band into a fixed Ku-band second converter, thus eliminating the image response without tunable preselectors.
