MIXER PRODUCTS
MITEQ’s DB0218LW2 mixer is constructed of a balanced diode quad fed by microstrip RF and LO baluns and a
DC-coupled IF structure. The construction, coupled with the hermetic packing, provides for high inherent reliability
and performance over an extremely broad frequency range. This device performs as an up- or downconverter cov-
ering most EW bands, utility testing and breadboard applications.
