MIXER PRODUCTS
MITEQ’s DMX and DMY Series of mixers are constructed using double-tuned microstrip RF and LO baluns with a DC-
coupled IF structure. The construction, coupled with the hermetic packaging, provides for high inherent reliability and
isolation over an extremely broad frequency range. This device performs as an up- or downconverter covering most EW
bands and communication applications. This mixer is also available with medium or high forward voltage diodes (M, H) yield-
ing proportional changes in LO power and spurious performance.
