MIXER PRODUCTS
MITEQ’s DM0520 Series of mixers is 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 high forward voltage diodes (H) yielding proportional changes in LO power and spurious performance.
