MIXER PRODUCTS
MITEQ’s DM0812LW2 mixer is constructed using new, highly efficient, 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 octave frequency range. This device performs as an up- or downconverter covering most X-band and
communication applications. This mixer is also available with medium or high forward voltage diodes (M, H) yielding pro-
portional changes in LO power and spurious performance.
