The SYSMM3X3638 is an integrated low-noise converter with internal image filtering and LO multiplier. The inte-
grated LO multiplier provides higher front end compression point than would be possible with a passive sub-har-
monic mixer. Internal LO filtering reduces spurious and fundamental LO leakage. All devices are screened to MIL-
STD-883 method 1010 and 1008 prior to hermetic sealing for high reliability. The single piece housing is a robust
mechanical design for ease of use in any system. Waveguide inputs, alternate frequency bands, and quadrature
or image rejection style units are available. Please contact MITEQ.
