MIXER PRODUCTS
MITEQ’s DM0408 Series of mixers are 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 reliabil-
ity and isolation over an octave frequency range. This device performs as an up- or downconverter covering satellite and
communication applications. This mixer is also available with medium voltage diodes (M) yielding proportional changes in
LO power and spurious performance.
